sorry I missed your pm(was at work)......but ya, +3 (Kien, Kevin)......the big section would be great for whatever skimmer you
ever decide to go with......have your drains dump as close to the outside edge of the big compartment as possible......if you want to run filter socks, a holder could be done with glass or acrylic or even eggcrate.....skimmer then fuge/spare rock (partitioned off from the skimmer with eggcrate).....bubble trap then return.....a nice tunze ATO and Bob's your uncle
