Good water conditionerThis water conditioner does its job; it removes chlorine from tap water. My only complaint is that the dosage on the instructions is given in drops. For my 2.5 gallon tank, I had to put 25 drops. Fish owners with larger tanks will have to put too many drops; an inconvenient measurement. The bottle is small, and anyone with a larger tank will use it up rather quickly.
