algae problem is becuase I havne't cared enough about the plants for the past few months. I have about 3wpg, that's on for about 12 hours a day with a 1 hour siesta in the afternoon. I feed my fish roughly every day, but I often let them go without food. I also feed them sparingly, not a single piece of food ever gets more than 1/4 of an inch from the water surface. I was injecting CO2, stopped a few months ago, started up the system last night. I need to add more charcol, I'm going to start with flourish, and hopefully the new plants will all keep the algae down. I need to start removing it sooner too.
