Attaches to 1/2", 3/4" Loc-Line and creates random flow patterns.

Vivid Aquatics 3D printed random flow generators easily snap onto standard Loc-Line segments for a custom flow pattern through their patent pending randomized design. Each RFG is made of reef-safe PETG plastic and made to outlast your aquarium. Just snap the adapter end onto either 1/2" or 3/4" loc-line and within seconds you can direct the nozzle with the traditional ball and socket style.

Two Sizes Available:
1/2" Loc-Line
3/4" Loc-Line

Randomizer
Vivid Aquatics revolutionary design uses a set of 5 fins in a spiraling design that channels the water in from one direction at the base of the eductor and then out of the nozzle a different direction. The small amount of interferance at the base of the eductor helps create a random change in the intake affecting the flows path exiting the nozzle.

1/2" Specifications:
Dimensions - 2.25" L x 1.3" OD
Min Flow Rate - 120 GPH
Optimal Flow Rate - 300 - 450 GPH

3/4" Specifications:
Dimensions - 2.75" L x 1.7" OD
Min Flow Rate - 200 GPH
Optimal Flow Rate - 420 - 500 GPH

Whats Included?
1x Randon Flow Generator Nozzle
 
There's actually three sizes - I'm using a pair of the 1" versions. They friction fit right into the end of standard 1" PVC pipe. I like them. They don't put as much back pressure on the pump as the old educators I had been using, and they do produce a more chaotic flow.
 
Good to know, I ordered 8 3/4” ones for my one closed loop. I have 2 1” outputs on my other closed loop. Maybe I should order 2 1” ones for those.
 
Looks like an absolute waste of money IMO..

The video and "random pattern" is less than impressive to me..
Its such a minimal effect that I can't see how its beneficial in any way..

Not to mention is 3d printed on top of that..
 
What's the problem with 3D printed?

Its not injection molded..
IMO...3d printed is fine for DIY projects,etc... but I don't believe that professional companies should sell FDM 3d printed products..
They really do not have the durability of a properly molded product.
I would have used the money they wasted on the patent for real injection molds instead..

Its just unprofessional IMO..
 
Cannot speak to the longevity yet, since I have only been running them for four months; but all of the 'superior' injection molded educators I have used ended up splitting. As to usefulness, who knows. There's a long list of things in this hobby that people swear by that are various incarnations of snake oil. And I'd bet even the most cynical and experienced amongst us has at least one of them :lol:
 
Not a total waste of money at all. I have one in my Reefer Nano and it's the sole source of flow. The water leaves the nozzle at 30 degree angles and it most definitely creates random currents in the tank. Just put one downstairs in the holding tank yesterday I like it so much. The thing is ingenious.
 
I've been using mine, a pair of 1/2" for 3.5 months. I have a 45 gal display and run the return pump approx 400gph after head loss and this is the only flow generator in the tank. No powerheads in the tank. with eduction, the flow will be a bit higher in the tank.

the only downside is the loclines need to go a bit lower under the surface so eduction does not suck in water from the surface. as a bad side effect, it fills my sump up with a bit more water when return is off.

This would be perfect for your closed loop, as you will not have the sucking air issue.

since this is 3d printed, you can see the 3d printed lines on the surface and algae and crud starts building up and may be harder to clean unless completely removed and soaked in vinegar solution. I have not cleaned them yet since installing. This is a minor issue.

overall, I think so far so good.
 
oh, BTW, if you get it, do not adjust it too much. since it is 3d printed, it will become loose sooner. If it does, I think VCA will replace them. I adjust mine on the locline segment it attaches to instead of the RFG nozzle itself.
 
I have noticed the loosening and adjusting from the loc line isn't an option with the Reefer adapter. It stays put for now, but if it gets worse I'll contact Antonio at VCA.
 
I ordered 8 3/4" ones for my closed loop with the Abyzz pump. I also ordered 2 1" ones for my closed loop with the Red Dragon Pump.

If they become loose I can just glue them to one piece of loc line. The 1 " ones slip on a piece of PVC, I may glue those as well but not sure yet.

I got notice a few minutes ago they all shipped so I will be testing them soon.

are you using one abyzz pump for 8 3/4" output
and one red dragon for 2 1" output?

how many drain/input going to each pump?

the drains/input must match the outputs. like one 1" drain to four 1/2" output.
and you can use dc controllable pumps to vary the flow some more.
so for each 1.5" drain, can handle up to four 3/4" outputs.

I have one 2" bulkheads for inputs on each pump. Both are plumbed and running great currently with 8 Penductor/Eductor 3/4" on the Abuzz for outputs and 2 1″ Omni Flex Nozzles on the output of the Red Dragon.
 
I like them. Only downside is what doughboy said you have to run them a little lower in the water to not suck air. So it fills my sump a little extra when I stop return pump. I mostly wanted a diffuser that didnt reduce flow they do that well.

I have a redsea and I REALLY like the 25mm to 3/4 loc line converter they have. That to a 3/4 to 1/2 locline Y is great!!
 
I am using the 1" on my Sea Swirls I really like the randomness-just helps create a different flow in the tank. I took a 2" length of 1" pipe heated it in the middle and gave it about a 22.5 degree bend so it faces down a bit so it is low enough not to suck air but still agitates the surface and does not make any water splashing noise.

The guy ripped the design off from a guy on Thingivese without even asking for permission etc. Super Shady IMO
