My 32g tank has been a real problem for quite a while now. I just cant seem to get the algae under control. Today I decided it's time to do a full rework on this tank. Pried off all the coral frags and removed all of the rock. Scraping all of the algae off the back as possible and scrub the rocks clean. and finally about a 75% water change. It is quite a chore but I hope this will solve my algae problems, or at least get it down to a manageable level.
