Does anyone know how to get rid of black hair algae?

I'm assuming you mean BBA, so make sure you have no "dead spots" in your water circulation, try to increase your CO2 slightly (if already using it), start using CO2 (if not already using it), and/or get a SAE.

It could be BBA if its really short algae. If its long it could be Stanghorn.

Here is a web site that may help. http://www.theplantedtank.co.uk/algae.htm
