Hi, I have a Nano with a nicrew led light which offers a medium light level. I've been having a problem with hair algae growing in my Java moss which is bound to a piece of driftwood which extends into the upper portion of the tank (to give a tree effect). The hair alage is pretty much only in the Java moss and often ignores the upper leaves of other plants.

I removed a portion of the moss and placed in a bucket for 3 days in the dark with some algeside in the water. It was seemingly all gone when I replaced it in the tank but it seems to be coming back. How does one treat and prevent hair alage from appearing in the upper portion of the tank?

How long are your lights on? More than 6-8 hours are too much.

Hair alga isn't too hard to control, less light & manual removal. You, after that, might look into Excel, but only after trying easier remedies. Some plants like vallisneria & anancharis hate Excel.
