Verified Purchase

My pool was quite disgusting when I opened it for the summertime, I had the shock at several times just to turn the water to a normal color. The alkalinity increaser was very necessary after these treatments, and Walmart gave me a great price and a quick delivery for me to be able to swim before the weekend began.

Customer Service

I purchased this item with 2 others. This item failed to ever show up. Called In the Swim they assisted with Fedex in tracking. . . . waited a few days to see if item would show up. Never showed, reached back out to In the Swim and no questions asked they resent the item and it showed up within 3 days. 10/10 experience and pricing. Definitely will buy from In the Swim again.

Our pool water tends to

Our pool water tends to have a low PH quite often. This alkalinity increaser always get it back in perfect range. It is so easy to use by just broadcasting around the surface of pool with no premixing required. The 50lb bucket is a very good value.
