Good advice given.
As for filters, pick one that is easy to maintain as the more frequent you service it, the cleaner it and you water will be, not to mentio lower DOC's and NO3. When using canisters, use lots of mech media, floss works well, remember to clean it or toss it as needed. A good skimmer is the best investment IMO for a FOWLR, especially on heavily stocked. Mine pulls out the nastiest crud you have ever smelt!
Good luck
