Thanks for the very thorough review. Nicely done. Can't wait to see your review with the 1/2 in in your Nano. Quick tip - you can tweak the position of the nozzle on the end of the loc-line to get a more randomized pattern, particularly at the lower GPH ranges. The best position is to have the RFG straight to the last piece of Loc-line.
I use this on my return pump. I seems to make the flow more gentle and somewhat random. It did not seem restrict the flow, the overflow adjustment on my redsea is pretty twitchy and it didnt change. Overall Im happy with it. The only drawback I had was the back of the nozzle has to be deep enough not to suck in bubbles. When you stop the return a bit more water syphons into my sump.
The little adapter they make for the redsea to get to a standard loc-line works very well. Been using that a while, I just added the random flow nozzles.
Just added this to my 13.5 g nano tank...I am still using the stock pump which pushes 135 gph but am very pleased with the amount of random flow generated. I am considering a more powerful return pump but even now I am very happy with this purchase. Down the road I will remove my wavemaker so that I do not have any moving parts in the tank. My Tailspot Blenny likes to hang out in the wavemaker when it is off and as cute as that is I worry about his safety...lol As a bonus my little clownfish loves to swim up to the RFG and ride the current...fun to watch! Thanks for the review!
The thingiverse model was the first one out there. Antonio Gutierrez printed the original model on thingiverse and posted that he printed it on Jan 3 2017, one month later feb 20 he registered the website. He then modified the ID fins slightly by increasing the size of the fins to the centre of flow, which would increase the random flow. I also was originally playing with this and set on an ID that matched my tank. He then began selling providing no source to the originals. So the thingiverse isn't a knockoff, it's the original where i created it nearly a year previously, and shared it in sept of 2016. I had the same thing happen with my microfishing rod, someone started a kickstarter with a slightly modified version, providing no source or props to the original design.
I added the other designs i tested previously. I only uploaded the one that worked best in my tank originally. The spiral design is specifically for randomizing and causing turbulent flow meant to disperse, this is why i provided an original flow educator and then the one with the spirals, because they were for different applications. With my pump and old tank it was all over. I had to tone it down and change it. Originally I had a center part which forced all the flow to be random. This was way too much for my tank. This original design and my step changes are now uploaded on thingiverse. Took a while to locate them on the drive. When you said the thingiverse design as a knockoff, this is not the case. As this was the original design and the root of RFG's. This is why I replied to your video as the statement was implying i copied RFG design. I worked at the time designing equipment for flow and erosion. I ran the numbers and CFD simulations on the designs when it was slow at work. I tested them in the tank, used them for a few months, and then got rid of them. I decided i was going to put in a wave pulsing system that just seems to keep the tank clearer.
Doing peninsula flow is tricky! i had a few mp40s along the back wall which cleared it up. Anohter trick i did is only have one pup on the overflow wall on for 20-30min to circle the water in the tank and clear any surface protein layer
ReefDudes Thanks so much for the pointers ! I’ll look into implementing those for my tank. I currently have got some biofilm at the far end of the tank that never makes it into the overflow haha
ReefDudes i was being lazy and hoped you would just know because of your legendary status. I will have to measure it when I get home and I’ll check online to see the sizes etc. 👍🏾
CUBAN REEFER - the bubbles are used just as a visual tip showthe flow pattern. The RFGs do not themselves produce bubbles, unless they are not fully submerged. Hope that helps and if you have any questions, please feel free to contact us.
Hey Dev the website says 7-800 GPH for u have any estimate on what you were flowing with the rfg when u turned up the pump and got more randomness. I just got 2 for my 75 gallon sps dominant

Micro bubble generator works great!
haha yes!

Good to hear yours is working out for you! im going to be adding it to my red sea nano as well! :)
The little adapter they make for the redsea to get to a standard loc-line works very well. Been using that a while, I just added the random flow nozzles.
I have one of these on my tank and I love how it helps my flow become more random especially when interacting with my Gyre pump.
Awesome! Mixing differen types of flow is the way to go!

I printed the thingiverse one and tried it first.. works more as a flow accelerator, he def modified it a bit to change the flow pattern.

If i wanted to modify the thingiverse version for a slower but "wider" flow, would that just mean flaring out the bell of the nozzle more?
Great video. Might need to see if I can get one of these for 1.5" PVC. Adding the bubbles was a great visual to see the changes in the flow pattern.
AlexGs Aquarium thanks Alex!
Do you have surface skimming blind spots since your outlet is on the same side as your overflow ?

Great review! Thanks for the video.
I have the RFG on all 3 tanks I own. I think it works best with a return pump that can be adjusted (dc). But it still works great on my Max Nano.
Awesome to hear.. im excited to see how it does on the nano later this week :)
Great video dude. Do you think this will fit onto the outlet on an aqua one minireef?
Do you happen to know what size the output pipe is?
ReefDudes i was being lazy and hoped you would just know because of your legendary status. I will have to measure it when I get home and I’ll check online to see the sizes etc. 👍🏾
hahah I have never seen that tank so your going to have to measure :P
Are those bubbles produced by the RFG, I ordered for my RedSea Max S-650 LED But if they produce so much bubbles I don’t think I like that
CUBAN REEFER nope. I put an air pump in front of the pump so we can see the flow

Hi. Does the RFG nozzle always spit those bubbles??
George Arias no. I put air through it so you could see the flow pattern.
Hey I know I'm a bit late to the party. Do you have a link where to download the one you 3d printed or maybe an updated model potentially?
Found it online. But honestly the legit RFG one is cheap enough and works better to just support it
Look forward to seeing a review of this on the nano
How did this go on the red sea nano max?
I love these on my 93 gallon. I kind of want to see if you are right about not needing my wavemaker since it is a cube and I have a 1600 gpd pump.
The wider flow seems to work better. I would like to see how it works on the nano.
SC Reefer I think it will shine in the nano! Hopefully find out this week!
Good informative review

Good Video- Not for me too much crazy current!
Thanks you! On a side note crazy currents are much better than laminar flow! :)
Very good video
good stuff...thanks for sharing....
Great info, hmmmm 🤔🤔🤔
Something to think about
To many bubbles for my liking.
haha they are just there to show the flow :P
Looks like it's makeing many micro and macro bubbles witch annoys some things.
