Ideal for spas with mineral systems and compatible with chlorine and bromine sanitizers, it dissolves quickly to maintain clean, fresh, and clear water.

## Description

Replenish is a 4-in-1 blend that combines the power of Oxone with chlorine to shock, oxidize, buffer and clarify spa water. It is ideal for spas with mineral systems and is compatible with chlorine and bromine sanitizers. Replenish is completely soluble, dissolves quickly and keeps spa water clear and inviting. Applications (Directions for Normal Bathing Loads): For most spas with normal bathing loads, Replenish should be added after every use and once each week for maintenance. Add one and one-half (1-1/2) ounces of Replenish for every 300 gallons of spa water uniformly over the surface of the water. Apply when the spa is not in use. Each ounce of Replenish will raise the free chlorine concentration by about 2 ppm in 300 gallons of water. Test the sanitizer level prior to re-entry to ensure the residual sanitizer concentration is between 1-3 ppm.

Review: great product - This product keeps our hot tub looking and smelling fresh. I put a small amount in after every hot tub use and I never have a bad smell and it keeps the water quality exactly where it should be. Very minimal efforts to keep the hot tub water clean. The size is good for one season.
Review: Great product! - Awesome price. I love this product more than what we were told to buy at the spa store. Works way better than what we were using, and haven’t had to drain the hot tub since we started using this.
