Anyone use one of these for their tank return?

I have two of these off of my scdw. I have no complaints with mines. You should be able to find them at any LFS.

I drilled a tiny hole in each a tad below the water line to prevent back-siphoning if the power were to go out.

How many inches under the water do they go? Thanks

under water far enough to get some water movement on top of the water drill a small hole just below the water level in the tank then it will not back siphon on you i use one on each of my returns to the tank

I believe that specific one will go under water about an inch. I don't have that specific product, but I use something like that that I built from pvc parts that serves the same purpose. If you have any pvc parts lying around, I would just make it. You could probably even buy the parts and come off cheaper or about the same and have leftovers for more if you wanted.

+1 and clean the little hole regularly as it will clog and not break siphon!
