My filtration setup is two of the aqueon 400gph filters(rated for 90 gallons each), and my diy overflow with 30 gallon sump. Basically a 200 micron filtersock then a five gallon planter filled with golf wiffle balls, return is a quietone 2200. I change out my filtersock every week and it gets a clorine soak and then 3 weeks of airdry before rotated back into service, (4 socks). I change two of the aqueon filters every two weeks, and do weekly 60 gallon waterchanges. Currently stocked with 1 oscar 2 sevrums 1 green terror 1 jack demspy 1 firemouth 1 eartheater and 1 common sailfinpleco. Does this sound about right?
