I haven't changed much I got the brown algae when I started using my light it increased when I started setting the times on my t5ho, then after a couple days it turned the green color. I was actualy plaining on going down to keys to pick up a cleaning crew this weekend.

It turned green almost exactly the same time my nitrate nitrite and ammonia levels went down to zero.
