Tank has been up and running for just over 2 years. I do bi-weekly water changes, and have a protein skimmer and U.V sterilization light as well as added phosphate remover a couple month ago. Have urchins who avidly eat the algae as well as a very fat and happy lawnmower Benny! The hair algae is always kept short but there are still traces on my rock scape which is unappealing to the eye. Any suggestions as to what I can do to eliminate this problem? (Positive it is not cyano just to rule that suggestion out)
