I know that others will probably disagree with me and that is fine. But for mujano anemones, I highly recommend Aiptasia Away produced by one of our sponsors: - Sea Life Aquarium Services & Supplies, 174 Semoran Commerce Pl. Apopka, FL 32703 (407)889-9887. I had a tank that was overtaken by them and I pulled all the rock and gave it a 2 week hydrochloric acid bath. I also had some problems at school in the 300 gallon tank. I used Aiptasia Away and the mujanos were gone with one application, even though, I was told that it might take two applications. They have not come back.
