Why Alkalinity Increaser For Pools is Necessary
I’ve found that keeping my pool’s alkalinity balanced is one of the most important parts of water care.

I also use an alkalinity increaser because it helps protect my pool surfaces and equipment. Low alkalinity can cause corrosion, etching, and damage over time, especially to metal parts, liners, and plaster. By keeping alkalinity in the right range, I can help extend the life of my pool and avoid costly repairs.
