Make your own great stuff in the diy section, I made my own wet dry with a plastic 3 drawer chest holds 5 gallon bucket full if bio balls still had space for more and I have 12L of bio rings under it and I have the heater in the sump (rubbermaid container) flows about 1000 gph (probably a little less but this is what the pump is rated for). In conjunction with this I have a fluval 405, ac110, and a emperor 400 for mechanical all on a 125 gallon definately overkill but it works flawlessly. I plan on making a larger one for my 265 gallon aquarium these diy filters work better and are cheaper to make than any filter you can buy IMO.
