Great video but the end is not satisfaing since there is no coment on what this number is. Is it a normal or it is not enough Ca or it is tooooo high??? 🤔
Hi...a quick question...does your red sea coral pro salt (22kg bucket) have any expiry date on them? If no ,then how do we know as to how old is the product?....
Salt, as long as it's kept sealed and dry doesn't have an expiration date. Each bucket has a bag inside with a seal, if the seal is there then the salt was not open and is as good as new, as moisture didn't penetrate and started affecting the salt's composition.
I struggle with this test and sometimes find inconsistencies in the results. When drawing the titrate into the syringe, slowly to avoid air gaps, the level of liquid within the syringe varies between 0.8 and 0.9 of a ml (when measured against the markings on the syringe). I understand that there needs to be an allowance for liquid sitting below the 0.0ml line so don’t expect the titrate level to reach the 1.0ml mark exactly but surely it should be consistent. Any tips?
How ever much trident is in the syringe just write it down then when the liquid turns blue just calculate how much is used, I have different readings each time when doing the test to but find that writing the trident level down the easiest way to work it out
They should have mentioned this in the video but the air between the plunger and the reagent doesn't matter. Just ignore it and read the level from the plunger before and after.
The air gap is the air trapped in the tip of the syringe. Ignore it and read from the bottom of the plunger, we have an illustration in the user manual(page 13): www.redseafish.com/wp-content/uploads/2020/07/Foundation-Program_Multilanguage-Manual_GB_DE_FR_SE_NL_SP_PT_JP_CH_20A.pdf
You can add more and add that amount. Multiply by 500ppmCa, the total amount of ml (each syringe has 1.00ml and each graduation is 0.01ml) If a fresh mix of Coral Pro yields over 500ppm that could be due to overshooting the salinity.
i have tes my aquarium using Big 3 tes kit from red sea, the parameter i got was, Alkalinity = 9 dkH, Calsium = 450ppm and the last one Magnesiumis the wierd one, it used 1,5ml titration to turn the liquid into blue, i have try 3 times and the result still same, so its above 1600ppm.. is there any problem with my tank?
@@Redseafish I have stopped when its turn to blue, but it used 1,5 ml of titrant. Is it normal? the other day i test it again, and the result still same.
After many years, I see a proper video. Never too late. Thanks.
Glad it was helpful!
Thank you for finally posting a proper video on the endpoint
Your welcome
0.85 where does it say that ?
You can see the calculation at @3:32
Looked blue to me before adding those last few drops 🙄
Great, thanks Li.

It shows the principle of testing and compliments the user manual and the color card where it's all stated clearly.
So is 420 good or bad you failed to mention that at the end of your video
That all depends on the recipe you're using. There's other parameters to match with it. Find your recipe here:

Thank you
You're welcome
Why do you leave air in te syringe? It's not really full... Tks
It's the air in the tip, it goes in the syringe and back to the tip at the end so it's not part of the count.

Are there any advantages to using your test kit verses a probe?
The accuracy, bang for the $... a good Calcium probe(that can test within +-5ppm Ca) can cost a small fortune.
Hi, can I use this test kit for fresh water also?
No you cannot. The coloration is calibrated to saltwater.
Can I use a magnetic stirrer while adding the titration?
Yes.
What does it mean if I use all of the titran before it turns blue?

Why dont you change the syringe so a person dosn't have to do the math or change the card to say not what was used but what left!
It's a medical syringe, very accurate and that's how it measures.
What if you use the entire 1ml and you never get that blue color? I use the Redsea Pro Salt.
You can add more and add that amount. Multiply by 500ppmCa, the total amount of ml (each syringe has 1.00ml and each graduation is 0.01ml)

With the Mg the end point is different, as soon as it turns blue the first time, you stop.
It will go back to purple, but do not continue.
@@Redseafish I have stopped when its turn to blue, but it used 1,5 ml of titrant. Is it normal? the other day i test it again, and the result still same.
@@holylight2037 same here, in that case whats the reading? Not much info out there if used more than 1.0ml
日本語ですみません。これは、1日１回ですか？
You test every few days at the beginning, once your tank stabilizes you can test once a week.
We have a manual in Japanese.
