Hi, i have about 150 lbs of live rock. They started to have hair algae and grew pretty long. I recently took all the LR that had hair algae on them and placed them in a large cooler with a powerhead inside. My tank also has green algae sticking on the side of the glass. If anyone can help me with destroying the algae in the cooler and keeping it out of the tank, i was greatly appreciate the advice. Is there any chemical i can place into the cooler or tank to get these algae problems out? Another question, I have my 75 gallon tank running with coral and fish right now with very limited amount of rock and two powerheads and a filter, the sump is also off (i'm planning to build another one), would that be okay for the mean time while i deal with the hair algae problem? Thanks in advance for the help.
