Quick update and advice request.

EDIT: String algae, not hair
Today I noticed the beginning of string algae on some moss and one of plants. I have been dosing to EI up till now.

I raised CO2 when I started EI dosing - 2.5bps to 4bps.

My instinct made me raise the light 2" higher to reduce PAR till I figure out what's going on. In the past this did away with the hair algae and it didn't come back.

Any advice on how to proceed? Raise CO2? Reduce EI?
