After fighting algae for over a year i drained my tanks, filled em with water and calcium hypochlorite, set a day, drained, rinsed, sprayed withphosphoric acid ( which cut the black buildup, im assuming at this point chlorine doesnt kill the crap). Rinsed, sprayed again, rinsed, drained, filled with fuel and power spec biocide. Treated the next 4 tanks with biocide too. MAKE SURE U GET ALL WATER OUT THE TANKS. Puting water in my tanks was my absolute last resort, i simply couldnt afford to buy biocide in 55g drums. Fuel is cleanest ive seen since i bought it, due for another rnd of follow up treatment though.
