The teaspoon of fertilizer I put in a few days ago really went a long way this time. It seems like I only need to keep the algae growing faster than the fish eat it. This time instead of cutting down on fish food I kept on feeding them heavily and there is no slow down on the algae. It is also very dark green. Perhaps the trick is to keep feeding them enough food so that they don't eat all the algae and I wont have to add anymore fertilizer. Or at least not as much.
