Poolife® pH Minus
Product Overview
High pH renders your chlorine ineffective; Poolife pH Minus is what pool techs reach for to restore chemical efficiency.
This 6 LB container of Poolife pH Minus utilizes Sodium Bisulfate at a 92% concentration to reliably lower pH levels that have drifted above the ideal 7.6 ppm threshold. In our experience, this granular formula is a proven choice for reducing both pH and total alkalinity without adding cyanuric acid or affecting calcium hardness. It is compatible with chlorine, bromine, and saltwater systems, ensuring your sanitizer remains active and effective.
Benefits & What Makes It Different
92% Sodium Bisulfate Concentration
This high-purity granular formula provides a safer, easier-to-handle alternative to liquid muriatic acid for lowering pH and total alkalinity.
Sanitizer Optimization
By bringing pH back into the 7.2 to 7.6 ppm range, you ensure that your chlorine or bromine works at peak efficiency to keep the water clear and safe.
Surface Protection
Regularly using this 6 LB balancer prevents the calcium scale buildup that typically occurs on salt cells and plaster surfaces when pH remains too high.

When To Use This
Pro Tip
If you live in an area with high evaporation or hard water, your pH will naturally climb faster; pre-dissolving the granules in a bucket of pool water before broadcasting helps prevent any undissolved product from sitting on the pool floor.
Common Questions & Instructions
How much Poolife pH Minus do I need for my 10,000-gallon pool?
To lower pH from 8.0 to 7.6, you typically apply 1 lb of this Sodium Bisulfate formula per 10,000 gallons of water, though you should always test after 4 hours.
Is this product compatible with saltwater or bromine systems?
Yes, Poolife pH Minus is a proven choice for saltwater, bromine, and mineral-based systems, helping to manage the natural pH rise often seen in salt-chlorinated pools.
How long should I wait to swim after adding pH Minus?
We recommend waiting at least 30 minutes to one hour with the pump running to allow the granules to dissolve and circulate before swimmers re-enter the water.
