This used to be a great valve but prices has got out of control.

Good price and available! Hard to find anywhere else

Price jumped 2/100 dollars. How ridiculous is that corporate greed is all that is!

Good price, free delivery

Reluctantly bought this bc I need it for the summer.

Great all around bulk shock. Cleared up a pool after a few days of heavy rain overnight back to clear

Cleared my pool at season open within a week. Must watch water chemical balance. After that, controlling well with tablets & mtce level algicide.

We've used these granules for many years for our commercial hot spring pool and found them to be effective.

Great product. Had it delivered with my plus membership. Sooo much easier than driving to the club, putting it in my car the lugging it to the shed.

I buy this about 3 times a year. We are lucky to have a huge pool; however, it does need lots of chemicals. I save about $20.00 each time i buy it
