Bubble Algae

:fish:My 75gal tank needs a complete makeover or something. I've got a tank full of LR and it's been taken over by bubble algae. I've tried water changes and critters but none don't work. Is there something more ballistic and won't kill my critters and fish to do? I have even thought about even buying new rock but, that stuff has gone up quite a bit since I bought this rock. Emeralds don't help what so ever and don't try talking me into those. My water is always great according to my LFS and they ask my why I want to get rid of the stuff, HUH? Don't understand them at all. There has got to be a better way??
