Hoping someone can help me resolve my brown algae problem. Was reading this is usually related to poor/excess lighting, poor circulation, new or unclean tanks. I have adequate circulation and great filtration with activated carbon, I do 15% water changes weekly with treated tap water. Lighting is not the case, lights are left on no more than 8 hrs. daily, and I have experimented with different lighting methods in the past. It doesn't matter if the tank is new or established, as my current one has been running well over a year. I have recently introduced live plants, had thought the plants would outcompete the algae for nutrients. Now I have brown algae growing on my plants. I was wondering if I should try a phosphate remover, or would this affect my plant growth? Anyone have a suggestion for a phosphate remover product? Advice much appreciated!
