New sump design...........hit me with some input

Well it looks really fancy. On the first drawing the baffle heights look good. I've found you need to have the socks about 2" above the water or they tend to shift out of there holder. On your second drawing Your sharpie lines show the water being about the same height as the sock holder. From my experience (what little there is) I think that you will find your water height will be too high in the middle chamber even with clean socks as you need to have a slight difference in pressure for the water to push through the sock. The other thing is you want to have the safety channel. If your socks plug up you want to have a way for the water to go over the baffle. Right now it would hit the floor. Not that 8 socks are going to plug quickly. Only other question I had was is there a specific reason for running 2 systems back to back like that? I have 2500gph running through 2 4" socks and the water still splashes into them making me think they can handle even more flow. Couple of 7" socks and you could run the whole amount through them. Then you got room for a refugium or frag tank. It's an awesome size, excited to see this one get set up. If its anything like your other tanks it'll be stellar. I like the built in chambers and ato. Good use of space.
