Description
SpaGuard Spa Sentry – 1 Quart
One-Step pH Control for Softer, More Stable Spa Water
SpaGuard Spa Sentry is a one-step liquid spa water balancer designed to help maintain stable, comfortable pH while softening spa water. It helps reduce pH drift, also known as pH bounce, so your spa water is easier to manage and more comfortable for soaking.
This 1-quart bottle is used after draining, cleaning, and refilling the spa with fresh water. SpaGuard Spa Sentry introduces a buffering compound that helps keep pH easier to balance while also softening water by removing dissolved calcium. As calcium is removed, the water may temporarily cloud, which indicates the product is working and the filter is helping remove excess calcium from the water.
SpaGuard Spa Sentry is a strong option for chlorine spas where pH stability, calcium control, softer water, and easier maintenance are priorities. It is not intended for every spa surface or sanitizer system, so compatibility should be confirmed before use.
