I have been offered an 100 gallon corner tank, for about $350 U.S. I want to attempt a planted Discus tank, mainly with Anuibias, floating plants, mosses, and ribbon like vals that the discus can swin through. My quyestion is, given that the tank has a filtration hole/filter section cut out/built in, what kind of filter can I use in there? If I am limited to sump and/or trickle filters, is that good for plated tanks?
