http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=algae-boom-in-established-tank#1 I have a severe algae boom in my 50 gallon tank that has been established for two years. The tank is home to a 5-year-old marble sailfin pleco, Kahotep, and a two-year-old pealscale angelfish, Goldie. The water is so thick with algae that Kahotep and Goldie can barely see. What is the best way to safely clear the water? Florrie 2011-05-23
