a brownish growth has appeared on the walls of my tank and on the plastic plants. i assumed this was algae so i purchased some algae destroyer liquid (.60% simazine) and treated the water 2 days ago. nothing seems to have changed. is the growth something other than algae? is it ok to retreat the water or will throw the chemistry out of balance? does the algae harm the fish or is it just unsightly? what do you recommend?
