Does anyone know what the maintenance schedule is for a Aquaone CF-1000 canister filter - i.e how often the carbon, bio balls etc should be changed/rinsed etc???
Depending on your carbon grade it could last from 2 weeks to a few months. Also depends on how much you have in your filter too. Bioballs should practically never be replaced. Filter foam (depending on if you have it or not) should just get rinsed in tank water and put back in the canister.
