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

I have been using this product for years and it performs very well. Cost less than pool store both local and mail order.

Disolves completely in a plastic tub before adding to the pool. The small scoop makes it easy to maintain the chlorine level i want.

This was the best deal we could find. A local pool supply company wanted $200 for 25 lbs! Don't wait, get your granules now!

The Member's Mark granulated chlorine is good quality and keeps our pool sparking clear! We have used it for years without any issues.

Delivered within 2 days of order. Same produce as in the store. I have used ths product for 15 years. Food quality much lower price than pool stores.

Great price, also quality product, gets the job done unlike other pool chemicals. Members mark keeps your pool clean and looking great!

I've been using this product for several years now. The price is good. The granules keep my pool crystal clear.

Great find for our pool cleaning supplies although the price went up!! Get em while they are available or risk losing out until next season.

last year I bought Sam's Chlorine and it was great! This year igot it and it was AWFUL! NEVER AGAIN!! It does NOT work I used a whole bucket in LESS than a month .
