thanks for the video share, dennis. how much flow do you estimate you have going to each or both through the single return? I always had issues with anything but medium flow passing through them as unless they were deeply submerged I would got vortices at the top of the water and introduce air bubbles to the tank. that and when pointed anywhere near the front of the tank water splashing and salt creep over the brace and edges. interested in your opinion with your brief experience as I see yours is just about the same height I prefer to run mine at. do they no longer have anti-siphon holes in the fittings? do you manage this with check valves and sump space to take on the extra volume during outage?
I mention in the vid that with a rough guesstimate I have about 650gph running through each one, so not a whole lot. I'm figuring a little over 1300gph total through my returns. Not as much as I would like from my Reeflo Hammerhead Gold return pump put that is after 6' of head height and water being diverted off in several places to feed other tanks. So with the largest 1" fitting, the flow isn't very strong. I could switch to one of the smaller fittings, which would give me a narrower but stronger flow.
No anti-siphon holes. No check valves. My sump handles the water volume with plenty of room to spare.
