Everything Dave said was spot on. Seahares will devour hair algae although I don't think you could support one in a 12 gallon long term, maybe one of the smaller species but definitely not one of the big pacific types. I would get a few snails and remove manually until you finish your algae cycles, usually a couple months but sometimes a lot longer.
