Does anyone have any data on how much GPH is reduced due to back pressure using the Custom Aquariums Siphon Stopper? I'm considering using two of these on a Innovative Marine 150 EXT. I've had a sump overflow in the past using the drilled hole at the water line due to debris blocking the hole. On my current tank I use a reverse check valve that has been working flawlessly for years, but this tank will be in an office viewable from the living room and there will be no canopy. I don't want any of the plumbing viewable.

I can't say for that specific product but the holes I have drilled on my lines never clog and act as a nice side benefit of causing surface ripples to help my Kessil's really shimmer. Obv every tank is different and with 2 returns it isn't too much of a problem if one was to clog. Looking at the device your referencing it doesn't seem like it would slow flow much and I am also an advocate for running whatever gph is near the minimum needed for your tank which on my tank is about 4x/hour but I also don't depend on my return pump for flow as I run MP-40s.

I'm thinking I will just T off a 1/4" pvc elbow right after the bulkhead at the water surface. It shouldn't take away much from the 3/4" return nozzle.
