Concentrated granular formula gradually raises the total alkalinity level and prevents pH bounce in spa water.
Alkalinity Up raises the alkalinity of the spa water. Helps prevent rapid pH fluctuation. A properly maintained spa should have approx 100-150 ppm.
1 1/4 tbs per 250gal increases by 10ppm
Raises the level of water hardness; helping prevent foaming and corrosion of equipment and extending the life of the spa.
pH Down quickly lowers the pH of your spa water. 100% Sodium Bisulfate
1/2-1oz per 500gal
pH Hold helps to manitain proper pH balance on your spa water. A single addition of pH Hold, when the spa is filed, will help maintain pH until spa is drained and refilled. Not for use on plaster spas.
1qt per 300-500gal
pH Up quickly raises the pH of your spa water. 100% Sodium Carbonate.
Hardness Control raises the hardness level of spa water. Helps prevent break down of equipment or damage to spa surfaces if water is either too soft or acidic. Calcium hardness should be 175-225 ppm
1oz per 500gal increases by 10ppm
