NOT sure if it was acropower. I know that people are using it with great success.All of my levels were good. I had this nasty brown stuff growing and no matter what I did it I couldn't get it to go away. I really believe that it was a bacteria bloom in the tank. Corals were looking great and encrusting and growing. The fish were fat and happy too. Sitting here looking at my tank I see pods,snails and limpets. Maybe I should have waited longer to cycle the tank. Anyway I'm gonna wait a few more weeks and then start adding stuff again.
