Well I had a few aptasia in my fuge and they kept spreading and so someone told be about kalkwasser mixed with water and you blast them with the mix. Well they are all gone now and I've had some hair algae in one spot and so I thought if it works that well on aptasia then why not hair algae. I sprayed the area up close with a syringe and the next day a good half of it was gone. I think the only reason it didnt get it all was because the flow blew some of it away.
