I wish I could find the reason for the hair algrea, my guess is high phosphates but Im not sure.
I use RO/DI bottled water - always have.
As for overfeeding, I probably underfeed. I only give the fish what they take out of my hand - nothing is left floating around the tank.
I also do 20% water changes everyweek and blow the rocks off with a powerhead. I'm not sure what else I can do?
The GHA is short at the moment maybe I should look at a lawnmower blenny for the time being and then return him to the store after clean-up.
