So we've remodeled our basement which housed all the equipment for the living room DT on the 2nd floor. I got a fish room!! I'm trying to re-figure the plumbing layout and thought you all might have some input. Cabinet on bottom and on top. I have a 29gal that I drilled high on the back glass to drain back to sump. Previously, I had a wye on the drain line and that fed the sump. It always seemed like there wasn't enough flow to the sump; more of a trickle. The 29 sits higher than the sump so gravity feeds the return to the sump. The sump has 2 inlets on it and I had previously used a wyes to feed them both but again, low to no flow on one of the 2 inlets. My tank only has on drain so not sure if I'm better off capping one and only using one. So I've attached a sketch of my intentions. Please feel free to advise, critique, or question my layout. Tank has been running for over 10 years. Currently a bit of a mess since taking the sump off line and kinda letting go autopilot while we did the construction. Looking forward to hear what you all have to say.
