Easy to use & effective
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 .
