So, I'm am planning the filtration for an upcoming 265rr (wanted the 300dd, but not enough room). Anyways I've decided to build a sump/ wet/dry myself using a 75gallon aquarium. The diagram illustrating my idea is below, please let me know if anything is fatally wrong. Basically the plan is in through media socks, through a drip plate into filter floss, over an eggcrate, through ~600 bio balls, another egg crate, then either carbon or foam into the sump area (not sure if carbon is needed since I'm using an autodrip that I'm plumbing through a water filter). In the sump area I will have 3 300watt heaters, the return pump (jaebo 12000), a small 392gph pump flowing to a 18 watt and 36 watt in line UV coral twist UV sterilizers, a 1" bulkhead to drain water as the level rises for a 1.5gl/hr autodrip. What do you think?
