Looked at them for my 2013 Red Sea S-400, but its recirculations pumps have to stay at a steady output to hold the downpipes water line. At that point would just be dealing with a directional swirling flow pattern.

Gyre type flow pumps are just a better fit, for the S-400's design.

These Random Flow Generators from Vivid Creative Aquatics are so affordable and effective I thought they deserved a QOTD feature! Plus we can talk about other ways to get random flow!

What are they? This is from the VCA website: "The Random Flow Generator® Nozzle. by Vivid Creative Aquatics can dramatically change the way water moves around your aquarium. With the RFG Nozzle you can produce a more natural flow pattern while also simplifying your flow solution. The RFG has not moving parts, which means it is reliable and durable in the harsh environmental conditions inside your reef tanks."

So let's talk about them and your experience!

1. How many of you are using or have used a VCA Random Flow Generator and what are your thoughts on them?

2. What other ways have you been able to accomplish "random flow" in your reef aquarium?

I recently set up my 425 gal tank and using the VFG on 4 return lines. I have return pump at 70% and you can definitely see the random flow working as it should. I can really notice it on my green star polyp rock that I have on the gravel bottom as the extended polyps sway back and forth in alternate directions.

The small curcualtion pumps along the back wall of this tank area actually perfectly suited for a 1/2in RFG. The stock pump is aorund 400-450 GPH, which is right in the sweet spot, so to speak, of the 1/2iun RFG

We have a number of customers using only RFGs in their 550 and 650s

I take that back mine stopped working took it out and cleaned it still not right. Seems to stuck in one position help ideas
Just replyed to you in the other thread as well, but just in case anyone else is tryuign to solve a simiar issue, I'll repost this here:

if it was randomizing as expected, but then one day stopped, there are few things that can cause this. The main one is usually some sort of obstruction inside the RFG. Usually a small snail or other debris.

Other possibility could be flow rate - at lower flow rates, the RFG can be more sensitive to the angle it sits on the end of the Loc-line at. It might be helpful to clean the return pump to ensure it's delivering as much flow as it can.

if all else fails, reach out to us and we'll take a look and see if we can help.

I run 4 on my returns. 2 per return. Im powering them with a jeabo dcp20000 set at 70%. This is on my 180gal . I definitely see an improvement in flow, that said i have a cp40 on each side, sow20 in each back corner, and 2 slw-20 in the middle. All of these are on else mode.
Ive got decent flow needless to say.

On my current build, a 400g and 320g displays im setting up closed loops. Im going to have 2 3/4 or 1inch rfg nozzles on each return, powered by the new jeabo mcd10000 pumps. Those are wifi app controlled. 4 pumps, 8 nozzles.
