In The Swim Alkalinity Increaser for Swimming Pools - 50 Pounds | 100% Sodium Bicarbonate - Raises Alkalinity and Balances pH Levels in your Swimming Pool Water

Works great as a pH increaser. Very good quality. Would recommend

I love to save money and this alkalinity increaser is far cheaper than getting at the pool supply stores locally. One disadvantage is knowing how much to use without having an analysis of your pool water. I go with a small amount of the increaser then test method using the 7 in one pool test strips. Use a bit then test it after a few hours over a few days until the test results are improved.

Chemicals delivered in tact and in perfect condition. Worked great.

Follow the instructions as listed and you will see it works great! Many folks just check ph and chlorine but really should check alkalinity as well. Price is reasonable and it’s delivered to your door saving you time and fuel and your back…

Does what it should. Price is good

Works well

Great price

I struggle with keeping my alkalinity at the right level, and this product works great. I just throw about a pound of product in for every point I'm low and by the next day all is good. Rather than buying the local pool supply product, I can save 20% and have it delivered.
