I only have a canister filter and a skimmer, i clean the canister filter every 3 days. Never had any issues doing so. If left to collect poop etc for weeks to a month then that would probably cause issues.Warning canister filters are not stable filters and can harbor nitrates and phosphates and I have seen cleaning them crash a tank if disturbed unless only carbon is in.
