Perfect!! That's exactly what I was hoping for. When I had my saltwater reef aquarium years ago, I was able to keep my fish and corals all in a perfectly balanced "natural" state without a bunch of artificial assistance, of course I had some. I'd like to eventually be able to do the same with this freshwater tank. Maybe in a year or so, I'll try my hand at adding some plants 🙂. But for now, I just want to get through the cycle and get things done right.
So with water changes (after cycle) to keep the parameters in check, the sponge filters will handle a fair bio load from larger fish? Would eventually like to keep a small school of angels.
