Rinse the balls in a bucket of old tank water at a normal filter clean to knock off excess mulm, and only add fresh balls from this pack to top up capacity or replace balls that have physically broken down.\u003c\/p\u003e\u003ch3\u003eSuitable for\u003c\/h3\u003e\u003cp\u003eFreshwater and marine tanks running the Bioscape Tropic Easy Clean 100 Hang-On Filter.
