I have been fighting a war with brown algae in my 40G tank for about 3 months now. It just keeps getting worse and worse. I have left the light out for weeks at a time and that doesn't help. I have reduced the amount of feeding down to almost nothing once every other day. I do a water change twice a week. It is just a tropical tank with assorted rosy barbs, giant danios, etc... There are only about ten fish in the tank total. What algae remover has people bought and used that works well and everyone recommends? Are those liquid algae destroyers good? Thanks for the help everyone.
