    Have you tested your water for phosphorus? Phosphorus is added to aquariums through fish food, some plant fertilizers and some pH buffers. Phosphorus encourages algea growth and if the levels get too high, can be toxic to fish. I struggle with phosphorus levels and have now switched fish food brands to a low phosphorus brand. This is having a slow effect at getting things under control.
    Good luck

    PS - good aquarium stores should be able to test the phosphorus levels for you so you dont have to get a test kit!
