Can u use these on closed loop constant flow pump or on something like vectra l1 on else mode?

Yes - in fact the close loop scenario is a very effective way to use the RFG nozzle. With their ability to randomize the direction and intensity of the flow, they can provide a very unique flow pattern that other solutions just can't match. Plus they can archive this at a wide range of GPH. The more flow you feed the RFG, the more pronounced the randomized effect.

This is not a closed loop, but it is a short example of the the RFG in a high-flow scenario. We added air to the line so you could see the flow exiting the nozzle.

They do need to be fully submerged to function properly, but the depth at which they need to be submerged is dependent on the GPH you're planning on pushing through them.

For instance, for two 1/2in RFGs at our minimum recommended GPH (250-400 gph) you could run them with the educator end of the nozzle as close as 1/2in to 3/4 to the surface, and have it not draw in air. On the other hand. if you run them at the suggested Optimal GPH (640-670), you may need to keep the educator end of the nozzle as much a 3/4 to an 1in below the surface. You could split the difference and run them at about 500 GPH to each pair, and still keep the nozzles within 3/4in range from the surface. That "should" give you enough reserve in your sump for comfort.

You mean combined two 1/2 inches are optimal at 640-670gph, not each 1/2", right? Because my 1" return splits to two 1/2" loclines. A split on the left, and a split on the right, for a total of four 1/2" pieces.

According to the tank manufacturer, each of the 2 overflows can handle 740 gph, and there's 2 overflows. So I would estimate each return (two 1/2" Loclines) would average between 600-700gph, for a total through the system of 1,200-1,400 gph.

It draws air towards where it connects to the Locline side, right? So if I have that part angled down, from the Locline but then have the actual RFG output facing more towards the surface, that would be the best way to back-syphon the least amount of water? So it would contact air at the exit of the nozzle instead of at the hole.

I'm probably just going to get a 2-pack to see exactly how it functions.

Correct - for two 1/2in RFG, the optimal GPH is 640-670. However, they will handle much more flow than that. The more GPH you push through e nozzle the more pronounced and chaotic the effect.

It draws air towards where it connects to the Locline side, right?

Correct - the educators are at the base of the nozzle body, similar to a standard accelerator nozzle.

So if I have that part angled down, from the Locline but then have the actual RFG output facing more towards the surface, that would be the best way to back-syphon the least amount of water? So it would contact air at the exit of the nozzle instead of at the hole.

Running with the pointed slightly up is a great way to position the RFGs - it creates a good surface agitation and keeps them from drawing in air at almost any GPH. However, the siphon will not break until the water level reaches the educator portion of the nozzle. So, you'll want to experiment a bit and sea what works best for you and your tank.

I'm probably just going to get a 2-pack to see exactly how it functions.

That's a good idea. We ship daily, so if you order before 3pm MST, we'll ship your order out today and you'll have them by Thursday at the latest. That will give the weekend to play around with them and se how they work.

Got mine installed today. Been in my mailbox for 3 days LOL. Anyway, I played with directions for about 45 minutes. Changed my gyre some too. Really liking them so far. Had to adjust flow and drain valves since they do restrict flow some more then the old fan tips. This is 2 3/4" nozzles.

Interesting setup. I like it.
How are the RFGs doing in terms of working with the laminar nature of the flow from the Gyre? is it helping to break that up a bit and give it some variation?

 

[TroyHoot]

I have the far side of the gyre going straight ahead. And the far Nozzle angled to middle of front glass. So those dont really interfear with each other. The close side of the gyre is angled more towards surface so I dont have the hard current coming back on the plate coral in lower left. The close nozzle is aimed towards left corner. So this nozzle makes for a random gyre type flow on the front side of the tank. I also run my gyre on random 10-40%. This is working alot better then it was before with just the fan tips on there.

So the close nozzle probably is helping randomize the far gyre that is angled straight ahead. The far nozzle is coming off glass and providing more random flow in the middle. I also have a pump on the far left in the back shooting across the back glass to keep from collecting junk back there. It is a constant flow pump. That may be changing.

So far the RFGs seem to be helping alot. Time will tell. I made alot of changes today with my flow. I will probably do more as i watch and see how the corals react and where im lacking any flow at.

I had been looking for a way to change my return flow and this was an awesome solution. My only complaint, which isnt a major one. is they are a little big. But I am running 3/4". I could use some 90 degree fittings and get it closer to the side. They just create more head pressure which I dont want. I could move my gyre to the other side but I would have to move my controller and all my wires. Had been thinking of getting another gyre for the other side. But these nozzles are making me reconsider that.

Sounds like you have put a lot of thought into the placement of all the components here. Keep us posted on the results. thanks for sharing!

Any Cyber Monday deals? I need to pick up 4 X 3/4" ones. I have been eyeing these for my system. I have an 1100 Gallon System with a 400 Gallon main Display on the main level with a basement sump, frag tank, etc. I have a Reeflo Hammerhead Gold returning from the basement via a 1.5" drain but it splits into 4 X 1" returns at the top of the Display tank. 1 in each corner. The 1" inch returns have 3/4" loc lines on them. I would estimate around 3000 GPH with head loss is pumping or 750 GPH per return (probably not exact as the return side has more flow than the other 2 that are 8 feet away). I will post some before and after Videos on my Youtube channel.

At 700-750GPH per return line a couple of RFGs would create an awesome amount of flow with the RFG ability to randomizing it. Would love to see that.

As far as sales go, we don't have any specific Cyber Monday deals at this time, but some of our resellers may. Check out our Were to buy section of ourt website at

Here is my Little update of my RFG from Vivid Creative Aquatics . I absolutely love them with my MP10QD ‘s turned off they do provide quite a bit of random flow in my 4ft 75g. I love them once again.

Here is a video of me showing them off with my build.

Super clean setup @Clayton Jessup . Really diggin' the sump area. Thanks for including the Random Flow Generator's in your flow solution and can't wait to see this tank come together.
Do you have a build thread here on R2R? If so post a link here so we can follow it.

Thank you very much Vivid Creative Aquatics for the kind words in my build. And yes I do have a thread going it’s called Embarking the Journey Reef build by Clayton

Here is the link please let me know of it works :

That looks great - I be those euphyllia are loving that flow. Looks like you're running the 1/2in RFG nozzle with the 25mm Slip-fit-drop Adapter - What size return pump are you using to drive the flow?

They do love the flow and there's no need for additional pumps anymore. I pulled out the 6040 which was almost too much even at the lowest setting. The RFG is a great solution for the close quarters of my REEFER Nano. An Eheim Compact+ 2000 is driving it.

I had to adjust my drain a little too but I bet the adjustment was barely 50gph. While the flow is a little less down the drain, the RFG has noticably accelerated the flow in the tank.

Installing mine in the next few days, I’ll definitely put pictures up when done.

1/2” still hanging out at hospital with my wife and newborn son.... soooooo I’ll get to it “eventually”

Plan was to do it yesterday or today until that whole labor thing decided to happen

LOL - having your priorities straight is always a good thing. New baby first - fun with fish & Coral.. later.
And, congratulations to you an your wife. ;Happy
