Just installed mine, have to find a way to angle them better to cut down on noise... but also not siphon more water than my sump used to with the old water return nozzles.
Flow is SOOO much better though, definitely happy I purchased a pair.
Oh and please don’t mind my GHA outbreak
I am trying everything to get rid of it ughhh

That should really get things moving in your tank - looks great!
As far as placement, here's a few photos I posted in a different thread that may help with placement and depth. These images are for the 1/2in RFG's but the 3/4in is similar but may require just a bit more depth - maybe about 1/8th of an inch more.
of course GPH plays a part in it as well - so experiment and see where it falls. We are working on getting flow test for each nozzle right now and hope that have that shortly.

Thanks for the photos. I’ll play with them later and see where the break happens vs too much sound of the turbulence breaking the water surface. I have video too, but have to upload to YouTube or something first.
Currently they are putting out about 1000-1050 gph combined between the two of them; 1600gph pump at 70% with ~4ft of head. Didn’t do exact math...

Stuffs like these aren't readily available in Toronto ... ya know?

We do ship to Canada, so you can order direct, but you are right - we don't yet have a Canadian Distributor... We are working to remedy that

Problem with shipping orders from US is we get tax on brokerage fee on top of what we had already paid for earlier thus making the products much more expensive ...

I am running about 350gph on my pair of 1/2" rfg, and every now and then, it will still suck in air from the surface. rfg is positioned maybe 3/4" from the water surface. I don't want to position it any lower as too much water goes back down to sump when return pump is off.That should really get things moving in your tank - looks great!

have you tried a design with no eductor opening on the top side? and/or maybe one with some kind of built in check valve?

We have not tried it with one educator closed off - but may be worth a look. The main concern here would be the reduction in the possible direction the stream can exit the nozzle, the educators, combined with the internal helix are what create the randomized flow.
Running a check valve would work - Loc-line makes inline check valves. My primary concern there is reliability.

That looks great @GatorScott. How long with just the RFG as your source of flow?

Since August. I switched to it because I felt like I had too much flow in my little tank with a powerhead for lps and softies. So I went the the RFG and upgraded to a little higher return pump to offset and it’s really made the tank explode.

Got mine about a month ago and it's a great product! Highly recommended!

Only reason I can't get this RFG, if I try to pry open the locline nozzle that is in my return line I am afraid I am going to break something. I have never been able to detach locline connection without breaking or knocking something over even outside the tank. Maybe I need to learn how to use locline

use two tongue and groove pliers, one on each segment and just pry it apart.

It can be pretty tough to get them apart. We use the two-wrench method just like @doughboy. Depending on how your tank is setup - this may or may no work for you but here's a couple of pics

I order mine shipped to TO. Shipping is about 10usd. Shipped using USPS, no brokerage. For me, no duty or taxes when received. Shipping was really fast, but the package was held at customs for about two weeks!
Great product, using it on my IM Lagoon 25.
