If im reading what you said right, your 5 degrees of KH and 7.6 PH comes out to about 4 ppm of CO2. Basically the same amount that is standard in any water left in the open. If you have a DIY CO2 or pressurized, check it.

As far as hair algae goes, its usually a very dark green color, not brown. about 2 -3 inches in length and i believe attributed to excess iron. If you see brown algae I would suspect a beard algae of some sort which is usually excess phosphates or bottom out nitrates. Can you test those two?
