Any creative advice would be wondrous. Main issue is space at this point. I don't want less than 100 gallons in my sump, and I'm running low on ideas. The overflow drain in my 65g would be perfect for releasing water into another chamber, but it seems as if it will be difficult to clean, and hardly worth the effort for 37 additional gallons. I have searched and searched for stock tanks that could either stand alone under my stand, or provide higher gallonage in the sub 10" height range. Nothing. Seems there are no 70" x 31" x23", or 70" x 31" x 9" stock tanks to be found.
That aside, critiques on this concept would also be wondrous. I have never put a sump together, but I think I'm on the right track.
