Balanced water is essential to soaker comfort, water clarity, sanitizer efficiency, and the longevity of spa surfaces and equipment. pH is the most critical factor. It is also the most sensitive, changing rapidly when bathers, products or other elements enter the water. When total alkalinity is in balance, it buffers the pH. When metals and minerals like iron, copper, manganese and calcium are out of balance, they can also damage surfaces and equipment. The SpaGuard family includes products to manage all these factors.


Spa Sentry™

The easiest way to control pH. Introduces an additional buffering compound, providing a dual buffering system. Expect up to three full months of clear, pH-stable water.
NOTE: Spa Sentry should never be used in spas with plaster finishes or grouting that contains calcium.

phincrs (1)

pH Increaser

Raises the pH (if it is below 7.4) and helps prevent corrosion.


pH Decreaser

Lowers the pH (if it is above 7.6) and helps prevent the formation of calcium scale.


Total Alkalitity Increaser

Stabilizes pH by balancing total alkalinity. Proper TA helps buffer pH to minimize the risks of corrosion, scale and soaker discomfort.


Calcium Hardness Increaser

Raises calcium levels to prevent the corrosion that “soft” water can cause.
