1-2804B Calcium Increaser for Swimming Pools, 4-Pound

I only received 25 pounds of this product and ordered 50 pounds. The box said there was 50 pounds in it, but there was not. Only received one 25 pound bag. Contacting Amazon about it was impossible with COVID-19. So I figured the only way to get a response was to write this reveiw.

Product did perform as expected. Should have raised PPM in my pool by approx 138. Ended up seeing only a 20 increase, last only 2 days and I was back at original. Very dissatisfied. Returned empty bags for a refund since cannot return product. Waiting to see what Amazon says.

Good value Vs buying from a pool store.

Works great to add calcium to my pool
