Brown algae on gravel and bio-wheel
I have an established tank that suddenly has a bad brown algae problem. It started about a month ago, and regular water changes and gravel cleaning isn't working. I'm careful about overfeeding and water tests show nitrates, nitrites, ammonia all normal. It seems my bio-wheel and ornaments have a pretty good build up of brown algae. Should I clean the algae off the bio-wheel? I'm afraid it will kill off the established bacteria. Maybe just take a dull butter knife and gently scrape the algae off the pleats of the bio-wheel without getting deep in between the folds? Also, should I clean all the ornaments and fake plants with brown algae?
