My aerobics septic system has 3 tanks, two of which are together,by this I mean first trap holds waste matter,the water is filtered into the bigger tank which has a pipe that you put 2 to 3 chlorine tab in(it's different than the tablet for pools)breaks down faster.than from there it goes into the third tank which(by the way stinks too)goes out to two sprinklers which are 50 feet and 100 feet away from the house. But all the tanks smell bad no matter what I do, the smell is not inside the house but in the tanks and srpinklers. Please Help.
