-If you have HOB only. You need to shoot for 10X turnover rate per hour. (HOB just arent as efficient as canisters, so you need some big turnover for only HOB)
-If you have canisters, you shoot for 5X turnover rate per hour.
Its always nice to have both canister and HOB so you get more aeration/surface agitation.
I have only canisters.
But I have THREE!!
I dont even know my turnover rate at the moment. But I have 2 Fluval 404's and a Fluval 304.
I get my aeration with my UV sterilizer that pumps out a lot of air.
