Swim got some ammonia and when he poured off, it smelled like it had some propane in the tank but still had ammonia smell. It also had a tint of red color in it(from rust in the tank it came from) so filtered it till it was almost completely clear, threw in batt's, and E. What Swim was wondering was if the tank had a little bit of any. ammonia and the rest was L.P., what are Swim's options or what should he do with his sludge because the reaction never turned dark blueish color,it almost wanted to but never did and the odor smelled like maybe there was propane in the tank before or gas or something, and after toulene was added and pulled a little bit and gassed it, it came back as E. Please Help?
