I agree! get a UV. I got a turbotwist. It cleared up my green water in a day and a half. Just make sure you do SEVERAL watrer changes to get rig of all the dead algae. Blackouts work too. i've done 3.5 day TOTAL blackouts to get algae under control before i had my UV. not GREAT for the plants, but all mine were able to tolorate it. I have 2 ehiems on my 55 gallon. The small eheim classic runs almost all checmical filtration. the larger eheim is all biological. I have the UV on the smaller filter so it has a lower flow rate.
