Algae

[benjoss]

Hi, I have a little bit of an Algae problem right now. How bad? It is covering all of the live rock and crushed coral. So probably pretty bad. The Algae started to grow rapidly when I upgraded it for a stronger light. I was wondering what problems this could cause for the marine life in my tank. Could this affect my Anemone? Also what can I do to get rid of this unattractive visitor. Thanks a lot.
