Can the majority of flow through the floor of the tank get the job done? I'm very seriously considering 3, 1 1/2" cl setups for my 320g 360 view tank (64" x 24" x 17" x 40" FBX... 36"s tall, bent edges. Centered 9" x 9" square overflow with 2, 1" drains, 2, 3/4" returns, and 1, 2" dry bay. Steve's Oregonreef.com is really inspiring to me. Most everything is out of view, and he seems to have the majority of his flow via cl through the floor under rockwork. What do experienced reefers think about the idea of having all rock built either on top of cl return plumbing as Steve did, or elevated just off the floor (1/2-1") by very small pvc support system (I'm going bb for about 70% and will have a separate canyon with sand). The idea being that one of the cl setups with 4 or 5 lockline returns could be dedicated to flow across the entire bottom under all of the rock and aquascaping. This would keep the floor and rock bottom squeaky clean of detritus. The other 2 cl setups would feed another 8 to 10 lockline outlets hidden through out the aquascape plan. My sump return through the top of the overflow would be max 1000gph... Does this seem doable, or am I going to have to have supplemental flow via Tunze or whatever higher up in the tank whether I like it or not?
