TAYLOR CYANURIC ACID DROPPER BOTTLE

Taylor R-0013-C-12 Cyanuric Acid Reagent 2 oz Clear. Taylor formulates its reagents to remain effective for at least one year, with only very few exceptions (molybdenum indicator in liquid form is one; after four months old it should be tested against a standard periodically). As a general precaution, replace all reagents more than one year old, or at the beginning of a new testing season.
