Ascorbic Acid (pH Decreaser/Cleaner) 10lb
When the pH levels of your pool are not maintained properly, the water becomes corrosive and can stain your pool. To get rid of stains, Ascorbic Acid is a great cleaner and pH decreaser! Ascorbic Acid is a reduction agent, the opposite of chlorine which is an oxidating agent. Ascorbic Acid reduces the iron in the stain from a solid state to a soluable state. Generally use 0.5lbs of ascorbic acid for every 10,000 gallons of water. It is recommended that you make a solution first (fill a bucket half way with your pool or spa water then add the ascorbic acid and stir until fully dissolved) then add the solution to your pool or spa, distributing evenly.
