The best kit you can buy. We have been using this kit since the early 1990's. Always accurate and true. The instruction guide and booklet is the best swimming pool water chemistry guide you can find. Complete with chemical dosage tables and charts really helps to figure out how much chemical to add. Muriatic Acid, Sodium Bisulfate, Sodium Bicarbonate, Sodium Carbonate, Calcium Chloride, and more. What ever you are trying to balance the Taylor kit is perfect for it. We train all of our employees to use this kit.
Comes with the excellent water chemistry guide and Saturation index chart wheel
