Hi Steven,

   Please do some water tests on ph and nitrates. How long has your tank been in operation? Please get back to me and I will try to help. Thanks, Gerry.

Answer
Hello again Steven,

    Try some algae eating invertebrates, and A lawnmower blennie or an inexpensive tang, or both, will help. Your store expert should be able to direct you to shrimps, crabs, stars and snails that will definitely do some good. The algae feeds on nitrates so if you starve it the problem will tend to disappear. Good luck and have fun, Gerry.
