So I just set up and started cycling my spare 20g for a brackish setup for an F8 and maybe 4 or 5 bbg's. My question is on filtering. I have a marinland 150 biowheel, using course and medium floss, bio balls and ceramic rings and no charcoal. I also have a PH30 powerhead with a bottle filter holding course and medium floss, bio balls and ceramic rings. My turnover should be around 9 to 10x an hr with that. Will those 2 filter setups in my 20g be good enough for 1 f8 and 4-5 bbg's?
