Best bang for the buck is what I use! Crystalline sodium thiosulphate. I get enough to neutralize 25,000 gal for $6. What would that much Prime cost?:dance2:
Ah ha! But sodium thiosulphate only breaks the chemical bond, leaving ammonia. Prime neutralizes the ammonia too, well, it bonds it into a safer form. Prime also detoxifys heavy metals. Probably a little safer for me coinsidering Im on a municipal water source in a major metropolitan area.
