Love the size that should get me longer than the small dripper we all get in the first water treatment kit.

Works like a charm. Don’t add it to your tank if you’re dealing with an ammonia spike - it’ll make it worse. Only add when your parameters are spot on and balanced.

Impressive product as it immediately helped increase my ph . Added in limited dosage as pkg suggested . Too quick a ph change probably not good for the fish so use intelligently . My ph had been low and caused cloudy conditions , but this solved that and clarity returned with normal ph .
