Yes, I have a Prizm skimmer, it works but if I was starting over again and wanted a hang on skimmer I would probably have gotten the Aqua Remora (I think that is the name).
If your fish store doesn't have ask around for people near you to see if they will give you some, it grows fast so often people just throw it away, or check online

Another alternative to that is running phosphate and nitrate removal media but I think you're better off trying to grow some algae, just my preference.
Either way the concept is the same, you are trying to remove phosphates and nitrates from the water before the hair algae can get it so you practically starve the hair algae off.
