I am getting annoyed at waking up every morning having to scrape off/clean the algae on the side of my tank. Now, I don't overfeed, my tank is not by any windows at all; however, I do tend to sometimes keep the light on a little longer 11-12 hrs a day, but I did buy a surge protector with a timer to solve that problem. I've tried algae fix, it kinda works but not really. I've been thinking about buying phosphoguard to put in my filter. Has anyone had any experience with phosphoguard, and does anyone do anything else that has proven to be effective against algae growth on tanks glass, rocks etc.?????
