Hello, I have a AquaOne AquaNano 60 tank with a Multi Stage Back Filter. I clean my filter sponges and change my carbon monthly however, today I have seen a lot floating in the water of my fish tank and realise that the glass at the back of the tank (where the sponges and carbon are kept) is covered in a thick orange substance that I’m guessing is algae. Should I clean this or leave it be?
