Just saw another video saying Hannah’s salinity tester almost crashed their tank. Seems like it’s best practice to have 2 methods to test or to only buy the Hannah if you’re willing to calibrate it over and over again. Glad your tank seems to be okay!
I normally just overfill my sump with saltwater so ato doesn't kick in.then the evaporation raises the salinity slowly. Love the channel never miss the live stream. 👍
When you use ghl equipment and the test water is wasted this is what happens longterm better with a xepta or alkatronic sp you can return test water, I told you that before mate :)
@@bopeep7806 I have to remove water to maintain salinity as my dosing slowly raises salinity. I think a GHL testing might help balance this problem.
Great to see an “expert” still has issues. Love the honesty. Quick question. My RO mixing container has a mark on it to fill too with the amount of grams of salt needed for exactly 35ppm. I just weigh out the salt and pour it in. Mix then test. I once got a reading that was a bit off so recalibrated and re tested (as same salt amount to same water ratio) and the level was correct before and it just needed calibrating. But at least this way it made me question my tester rather than trusting it initially which could of led me to do an incorrect strength mix.
Yup. salinity issues are a real pain and should not be underestimated! Have had this issue myself because of a faulty refractometer. If your salinity goes out of whack, a lot of your other parameters can go swing like crazy with all the problems that come with that. Luckily you caught it in time!
Your not the first to say this those salinity checker by Hannah have crashed a few tanks
When I was looking at refractometer‘s and salinity checkers, I had read that this one was not nearly reliable enough as it should be. So I opted for the optical refractometer from Milwaukee. Glad to see that you caught it though, thanks for sharing.
Glad you caught it in time Sir. No reefer wants to see another have a tank crash.
And TY for sharing your mistakes, it goes along way. We often learn more from mistakes and near misses than success.
The low salinity reading off by about 3-4 ppt is an easy mistake/situation to get. When you turn on the Hanna the default salinity before calibrating is about 3-4 ppt high. When you calibrate the Hanna, you press the Cal button. Later on, don’t accidentally press it! If you don’t have it in a test solution then it can restore the default. Thereafter it reads high so your actual salinity deviates from what you expect and the correction lowers the salinity as you try to correct it. Accidentally pressing Cal isn’t’t fixed by turning the Hanna off. Instead, press Cal again to exit the Cal mode. This keeps the current calibration. The Cal process is using conductivity rather than salinity to calibrate the Hanna which is why the same solution can’t be used to check an optical equivalent.
Caught a temperature issue today. Added my first bit of sps coral and have since increased light intensity, which looks like it’s raised the tank temp 1.5 deg c. Surprised, but can’t find another explaination
i do use hanna for salinity alk and phosphate i generally know how much salt by weight for my water changes is always correct i still do calibrate my salinity checker always been reliable however my hanna alk checker caused a massive issue when it was reading 8 consistently when i sent icp test off it was 13.5 tested it with salifert icp test was correct i now keep the reagent i the fridge and double check with salifert which to be fair for me are the most reliable test kits and not expensive
Alex, I also calibrate my Hanna salinity checker 2x/month like you do. I also have a Milwaukee which I use as a back up. Good thing you caught this issue when you did so you could rectify it.. 👌
I had 41 ppt salinity, refractometer was broken. Now, after having 40-41 ppt for 3 months, its around 37 ppt and most of the sps look better, most of them where almost white and i didnt know what i was doing wrong 😭. All my lps were puffed up and looked even better when they had high salinity. One of my euphyllias is as big as my fist (ony one head euphyllia) and torches looked so nice 😅
Just my two cents, but I really enjoy this sort of “authentic/vlog-ish” format. Of course, the circumstances that prompted this style of video weren’t ideal! However, I’d definitely be down for more videos in this format, such as periodic tank updates, quirks you run into, impromptu bits of advice, etc. It’s a nice change of pace to the typically very professional and highly polished videos you put out. At least for me. Again, I’m just some guy. But love the channel, and glad to see you were able to take corrective action and get the tank back on course fast! Happy reefing!
I do those sorts of videos on the Reef Dork Xtra channel - there'll be one this Sunday with an overview of all my fish 🙂
@@ReefDork Noted! Thank you sir.
I had this issue with the checker back in August of 2022 but mine was reading really low. Long story short; most my tank didn't survive a large water change, and the checker was faulty. Contacted Hanna, even when doing the calibrations with their direct steps still would not read right despite their firm disagreement the tester was ok. I have since thrown that thing in the trash and no longer recommend one.
Interesting video Alex. My Hanna salinity checker (calibrated) reads 1 ppt lower than my LFS's Milwaulkee checker.
I have also had an issue with low pH even though I dose Kalkwasser with a stirrer in ever so small increasing amounts. I have two probes in the sump of my 320 litre frag tank, one made by reef factory and the second device by Neptune running in conjunction with an Apex.
Both are calibrated, the Apex probe with the 7 and 10 solutions, whilst the reef factory probe uses 4 and 7 solutions. I was hoping that Reef factory were going to change their calibration solutions to bracket sea water values, but that has not happened yet. The issue I was having was the Apex reads higher than the Reef factory probe by approximately 0.46 of a pH measurement. I have recorded and graphed a 24 hour period of both probes.
I purchased some 4, 7 and 10 standards rather than keep paying for over priced standards from Neptune or Reef factory from a company called APC in the UK. I have checked both my pH probes with 4, 7 and 10 pH standards and interestingly find my reeffactory probe will not reach read the 10 standard, the maximum pH it reads is 8.78.
Now I am more inclined to beleive the Apex probe now and see I have a more realistic pH reading, (i hope).
My Hanna salinity checker was off! It was telling me 1.026. After calibration the tank water now reads 1.031! Thank you so much. I’m going to rescue now lol.
I recommend the Greisinger G1410 for salinity.
Thank you for sharing. I had my salinity spike after I accidentally left my ATO off for 2 days. Quickly recovered but scary!
I had a similar issue. Since then, I decided that I will always double check my salinity with a refractometer from now on when I mix a new batch. My hanna is great and all, but I can't fully trust it. The same goes for the refractometer, a slight nudge of that dial could move it a couple ppt off...it's always good to have a backup and if they are not showing a similar reading, you can troubleshoot before it becomes a problem.
For me, the Tropic Marin Precision Hydrometer has been the most accurate tool. No calibration, no doubts. Just works. Yes it’s big and fragile, but you just can’t go wrong
I've always simply poured some salt in the sump when I've had low salinity. It'll dissolve. Just add small amounts at a time. Works a charm.
Just went through the same thing. Recently tested my salinity and found it to be 1.019. My best guess is that during water changes, I have been removing slightly more water than I replace. Be sure to keep a close eye on Alk and Cal when raising salinity back up. After 2 weeks of slowly raising my salinity I found Alk to be 5.5 and Cal to be 250. Now I’m working on raising those back up.
Same exact situation happened to me with the salinity at 1.022. My fault as I was not calibrated my checker. I do it monthly now and always rinse with ro/di water. I like the Hanna tester but I wish I had the Milwaukee MA887 digital refractometer. The price that Hanna chargers for the packets is up to $27 per box. If they were half the price then it would be a non issue. Overtime the cost is spread out but reality is I’m paying for a 1oz packaged of saltwater, lol
Nice Recovery ! Check out the Tropic Marine high Precision Hydrometer . It comes in at a Whopping 14" & is fragile , but you'll never have to buy calibration fluid again . Deadly accurate ! So I'm told . Thanks & Good Luck !
Glad you managed to rescue the tank!
Goodness...a great video to us all. Off to calibrate my Hanna Checker now. 😂 I usually do it once a month aswell. How is the salinity in your other tanks? Hoping you get lucky with the recovery 🙏Thumbs up 👍
It was the same story in both other tanks! Both 32ppt but both look more or less fine, except for a tiny bit of sulking that's already stopped! Gotta love LPS!
So easy to slip up. Always worse when your remedy actually has an undesirable and unnoticed side effect. Glad you caught it in good time and thanks for sharing. Good luck with your corals' recovery!
So glael you got on top of it Alex and found the cause 👍👍, I had a similar problem in a sense my Tunze ATO failing dumping 10 litres of R/O water in reducing salinityto 1.021, me not paying attention and then boom my yellow SPS that's been thriving losing colour , sadly lost it, but back on track but as you say delayed reaction for SPS all the time😂
😕
Recent fragbox TV vid was slating the hanna salinity checker as one of March's staff had a tank crash because of one. I'm stressing a bit about using mine now after watcging this and seeing the comments 🙄🤯
I'll still use mine, I'll just calibrate it before every use now...
Even with calibrating properly, I had massive inconsistencies with the Hanna checker. I've found instruments that use refractometry as a measure vs conductivity like what the Hanna uses, to be much more reliable
My hanna salinity checker added .05ppt over night, read 1.39 every time after calibrating. Regular hydrometer showed consistent 1.34. The digital readers are great, until they aren't:/
Good video! I’m glad you took care of it!
Do u not have glass on the top of the tank like the old condensation trays? Or have they been proven to inhibit gas exchange.
No, they look awful and I want evaporation for kalkwasser purposes
Thanks for sharing that. Makes me feel better about the mistakes I've made in the past too!
I nearly did the same with my stirrer a few weeks ago. Hopefully its on the mend for you 👍
Such a simple mistake.. required a quite elaborate reaction. The thing we need to remember... The correcting action often may affect another thing in the tank. A plan A and B needs to be devised... The worse thing is to be correcting something and something else goes wrong. Glad you caught this. Salinity and calibration of refractometers/checkers seem to be something that is forgotten... But affects the entire tank.
It’s the one thing I’ve never invested in. I’ll always trust a manual refractometer over a digital one.
I have a Hanna salinity checker. Retired it about a year ago. Had to constantly calibrate it and it got me in a little trouble once or twice. Not worth the trouble IMO.
Thanks for the video and the reminder to calibrate my hanna tester!
Seeing the fan on the tank gave me Final Destination vibes.... 😅😂
You have made me just retest mine, please to say it wasent out at all after not calibrating for 2 months !
I do have some coral issues though I'm unsure what is causing it. I rely on Hannah checkers due to not seeing the colour blue on test kits but phos at 0.20 and nitrate 43ppm. Now this seems high but I've seen worse and as it's zoas effected only out of all my corals I'm confused 😂 are you fragging some zoas soon Alex ?
Similar experience for trusting the Hanna Pen. My fault though. I should have known better to check with my other devices. Salinity is definitely underrated.
This has prompted me to re-calibrate my hanna salinity checker and possibly get another methos of testing salinity. What would you recommend?
Refractometer
Blimey, good job you caught it though, all the monitoring equipment has paid off there, including the kalk stirrer. Glad to hear things are on the mend and hopefully the corals recover. Would a refractometer have possibly prevented the salinity drop due to the face you calibrate more often? I didnt realise the hanna one requires so much calibration.
Probs, yeah
Please everyone, do yourselves a favor and always always keep a Tropic Marin Precision Hydrometer. This is as accurate as it can get with no extra work or calibration. Yes it’s fragile and it’s massive size can be a hassle, but you can’t go wrong.
Fingers crossed for you buddy
Hannah’s salinity testers are very good [I also own one] but calibrating them every week or at the latest every 15 days as it says in the instructions is very expensive, at least for me. I think it would simply be better to have two refactometers calibrated using a liter of salt water that you prepare yourself following the instructions in an accurate way.
Thank you for making this video, after watching this I realised I hadn’t calibrated my Hanna salinity checker for a few months so after doing so I discovered my DT is at 1.023, perhaps this is the reason my goni is looking sad
Do you find your salinity checker calibrates well? I calibrated my brand new one last night and tested the calibration solution immediately after and it tested at like 34.7 ppt or something like that pretty consistently.
Yeah, it's fine on calibration even now at a year plus old. I'd speak to your Hanna if it's not perfect immediately
Did you know you can accurately calculate your salinity from an ICP test? There is a website where you enter the data and it calculates it. I like to do this to benchmark my salinity.
I always still use my refractometer and calibrate it every time.
Serious question because I would like to do the same: How do you fill your ATO without getting water everywhere and all over the walls (with it being behind your tank)?
Anti glug jerry can from Amazon
@@ReefDork like a can for gasoline/diesel? Is that plastic in that ok?
@@kaseyascani127 no, you want stuff made for food/water. LDPE and HDPE is safe.
Fragbox corals just mentioned the same problem with the Hanna salinity pen
See I never have a issue I always mix my salt at one scoop less then what they call for always keep my salinity at 1.025 stable along with an over powered octo skimmer
Hi reef dork!
You have probably already answered this in one of your videos or in your comments but why aren't you using your reef factory salinity guardian anymore?
It needs regular calibration like all probes and I can't be arsed!
Haha fair enough. How often does it need to be calibrated? Every month?
Good day.
Tell me, where is your ReefBreeders lamp?
Why did you abandon them?
I wanted more shimmer so I went for Kessils
The hanna salinity pen is the worst piece of equipment I've ever bought for my tank.
I've heard so many reefers have issues with them.
Mine was brand new, calibrated it everytime I used it and it would always show a different reading when testing the same batch of water, I noticed the slightest knock, even just placing it down would throw out the calibration.
Absolutely useless how it can read it's own calibration fluid vastly different when it was calibrated 2 minutes earlier.
I took great comfort in throwing it in the bin and going back to the old fashioned refractometer.
What tank is this?
Red Sea Reefer Peninsula 500
Obvious question but do you not have a refractometer as a back up?
Yep
Now I am here wondering if my salinity is correct, lol! I guess time to go made scientist for a bit?
Thanks alex i just went and calibrated mine.... my salinity is down to 1.022 as well... only calibrated two weeks ago ive been doing a series of big water changes. Is it worth getting a salinity gaurdian?
Same problem - you need to calibrate it regularly. If you can be arsed to do that, it's great. If not...
@Reef Dork ill stick with the hanna then haha 😄 i already hate calibrating the dd kh manager and ive only done it twice
Best bet is to have to two checkers to cross check them.
Hanna checkers are just not great. I used fresh calibration water with mine before use every single time. 1.029 was what it had my levels at when checking with multiple refractometers.
Same issue, Bought their cal solution and same thing....Never again Hanna complete junk!
4:31🤣
Get yourself a refractometer mate, Much more reliable IMO, and At least use it as a cross-reference!
This is what happens when you use ghl equipment to test as test water is wasted, salanilty slowly goes down :( Better use xepta or alkatronic so you can return test water to aquarium
👍
👍
👍 :)
you should get a mid grade refractometer, just to confirm your Hanna is correct.
My tank crashed but I managed to save all but 2 frags
Is the Montipora back from the dead? lol
Yep 😅
Voice-to-music ratio is too low.
As in music is too loud?
I calibrate that thing every water change for that reason
You calibrate a salinity checker every water change?
@@Merknilash yup. Sometimes it doesn’t need it but more than half of all water changes, it’s off
If I recall correctly even the instructions for my refractometer indicate to calibrate before each use. I do it every month or so using 35ppt calibration fluid and it’s only been slightly off once in several months. I think I’d lose confidence in a device that was off every time I used it, personally. If it works for you, it works. Happy reefing!
@@masheemashedpotatoes I use it daily, it could probably go 2 weeks or so but it has lost calibration after a week of use
Atacbey
Hanna Checker i wouldnt trust it at all.....i went back to good ole reliable refractometer to double check apex reading
Thanks for posting when things go wrong. As you say most people make this hobby look so easy, but in reality it’s not even close. Thanks again.
I wanna get a smaller and quieter tank that I can put somewhere I’ll see it and work on it more often but getting rid of my big fish, setting up a temp tank for the stuff I keep while I get a new one, actually finding someone to buy it for an alright price and setting up the new tanks dosing and everything all seems like so much effort.. I’ll just be patient and save some money so I can set up the new tank first, it’ll take longer but it’ll be so much simpler 🧘♂️🕋
Thank you for posting this! I just had a somewhat similar problem and almost killed my corals. My salinity was at 1.022 as I’m dosing kalk. I had the not-so smart idea of just adding super-salty water. My alk, calcium and magnesium went sky high and all the corals looked horrific. I did many water changes through DōS. Parameters went even higher. I dumped all my fresh and saltwater from the bins, thoroughly cleaned them, tried different salts, tested fresh, salt, other salt and tank water to no avail. I started thinking my RODI filters needed replacing, called BRS and was losing my mind. Exhausted , I took a rest and the thought hit me: adding 1.040+ water not only raised the salinity but the other levels. Also, emergency water changes do not work through Neptune DōS. I’ve been removing and adding buckets of water, carefully measuring salinity at every step. I’m still at it and things are a little better. Would you use coral recovery meds? By the way, when the Hanna checker reads a flashing 1000 for RODI, it means too low to read ;-) Thank you for mentioning calibration! I’m doing that right now. Am exhausting week lol
Oooohh - I need to calibrate mine (I got some calibrators with some corals and in my excitement threw them out) - but I have a hydrometer.
I'd rather be 38ppt than 32 and because of that try to run it a bit high (36).
I think temp swings lower are fine for corals - even much lower than that but at some point it stresses fish.
That Hanna Pen is garbage. Get a regular manual or digital refractometer. You’ll see how horrible that pen actually is. Tons of confirming reports online.
This is why I never trust digital salinity checkers (2 broken hannas in 2 years), always have a quality optical refractometet on hand to cross reference the results
Joys of a reef tank ........... told by the reef dork 😂 should have an apex mate ;-) lol
Until your Apex probe gives you a false sense of security until you calibrate it… Haha.
Just use refractometer, every time when I'm doing calibration turns out it is on perfect spot.
And here is another reason why I run nsw, mistakes like this are nearly impossible to make, nsw has made reef keeping with sps almost maintance free.
we did a water change and tested the water, all good. away we went, then when i tested my water the next it was through the roof. another quick water change all is good, close call and no idea what caused the spike
Scrap that tester and use a refractometer would be my advice ….
Keep it simple use a regular salinity checker ,nothing fancy
Yikes ! Close call
Thanks for sharing, happy for you that you managed to catch it in time!
reef tank blues
JBL hydrometer doesn't ever need calibration and is £15
Hydrometers are notoriously unreliable 😕
Throw away that Hanna salinity checker. I know of several reefers losing it all because if inaccurate readings from it.
Nah, it's fine - it just needs calibrating before every use
Hi, do you dose any trace elements when using kalkwasser please?
I don't, no
Having a similar problem as my ato broke while I was away and dumped the entire reservoir into the sump. Then the Mrs spent a week guessing at manual top ups if needed so was all over the place and water level was so low my skimmer wasn't pulling anything
Alex, question- what's the difference between the hanna salinity vs old school refrac? Are they many advantages of changes? I have every other hanna but hadn't even considered changing over for salinity.
Also, your tank is BEAUTIFUL!!!!
Mistakes like this are so valuable for us to share with each other, Thanks!
PS highly recommend the pin point conductivity meter, been using them for 20+ years.
And that is why I calibrate my refractometer pretty much every time I use it.
Takes 2 mins and is a lot cheaper than the possibe consequences.
Maybe just get a refractometer?
I have 2...
Sorry, I didn’t mean that in an intentionally rude way. I’ve just heard about this fairly often and not with refractometers is all.
Glad ur sorted pal, sps are not forgiving at all , but are the king of corals 😊
Great catch that could have been disastrous
I hope it all comes out well! I mean part of learning is trial and error, right?
I had the same issue with Hanna salinity checker as it was reading to low after calibration my salinity was 37.8 so I went back to TM glass Hydrometer
Get a refractometer and calibration fluid. They are cheap, easy to use, and you won't regret it.
I check mine every use and I've checked it against a $10,000 at work and it is very close.
