How often should I clean my Fluval 405? Its been cycled for about 3 weeks
I clean my 405 about every 2 weeks. I fill up a bucket with tank water, swish around and remove debris from the foam inserts and Bio-Max, replace the poly-fil, remove and clean the impeller, and clean out the actual canister with an algae sponge and tap water. About once a month I break the whole thing down and clean the input and output hoses with tap water and a long handled brush (lots of gunk builds up in those things).
