Puri Tech Chemicals pH Plus 5lb Resealable Bag for Swimming Pools & Spas pH Increaser Up Balancer 100% Sodium Carbonate Increases pH & Chlorine Effectiveness

Good price and product

I use this with borax and castile soap to make my own laundry soap and this makes it way more economical

Much cheaper than pool store and works great.

Not what advertised

Good size bag. Immune to humidity before opening. Good stuff!However, zip closing did not work.

Works just the same as the higher priced alternatives from big box stores.

Good price and a good value PH back to where it should be

adding product per directions and volume of pool adjusted pH to correct value/range, however product left pool cloudy/milky for days each time I used it. Reached out to seller, never heard back.
