So far ive used this to treat water for tadpoles, frogs, betta tank, crickets, dubia roaches, fruit flies, and plants. Everything has done better since i started using the conditioner and my water quality is not great. The cap on mine doesnt have measurements so i use a liquid medication syringe to do a gallon of water at a time. The bottle leaks when i shake it and it has an unusual scent if you care to give the bottle a sniff. Much better quality then some other zilla liquid products.
