I just recently found a 55 gallon salt water fish tank. Includes filter, heater, lights, stand, and 60+ pounds of live rock. Also includes yellow tang, 2 yellow tailed damsels, a sargent major and a large blue finned damsel. To me it looks like there is alot of brown algae everywhere, but right now it only costs $50 but there are still 4 days left to bid. He said i could buy it now for $200. What should i do, is brown algae bad for LR, like will it kill it? I would most likely get rid of the fish. Thoughts! PLZ HELP!
