Did you do the physical removal or just use H2O2?
Watch your cycle after using so much H2O2 to kill the algae and cleaning your filter at the same time The more algae you left in the tank to kill chemically, the more likely you'll have a mini-cycle if for no other reason than the dead algae will throw a ton of ammonia into the tank. Cleaning the filter at the same time may compound the problem. This is why I stressed doing a thorough physical cleaning before using H2O2 on a tank with so much algae.
