I have a 20 gal tank and my Bristle nosed pleco does not like to clean my aquarium plants so they have black/brown algae on them. I use algae remover and it seems to work. My problems is the filter extension that hangs in the water, the algae has stained it and I cant get all of it clean, especially at the upper most part of it. I was wondering what would work to clean it all off.
Thanks.
