Before using this product you must first drain and refill your spa and set the desired level of both pH and alkalinity before applying. Spa Sentry also contains a clarifying agent that removes dissolved metals in your water, giving your spa clearer and softer water that will be instantly noticed by bathers.

Cleared and tuned my well water! I'd give it 5 STARS but reserve that for "OH MY's"...

Good spa chemicals to use to keep your spa clean and the water safe and healthy. Best brand I know of.
