The Good news is that my Hair Algae problem is getting under control.
The bad news is that it is because it is covered in Cyano.
I had been doing everything right, water changes 10% or so every week / week and a half. Limit feeding to every other day and only a little at a time. Lights are not old. RO filters are not old. (less than 6 months)
So far no covering of corals and the fish are happy.
Going to move some flow around and do a little more water change. no chemicals here. Funny and I had dropped NEW phosphate not that long ago....
