Good product. Works. The only downfall is it doesn’t dissolve well. I just put it in a bucket of water to help the process. Still really happy with the product.

Great price when you break it down to a per/lb cost. This is not the typical shock formula but happens to be exactly what we use so that is a plus as well. An amazing value when compared to buying a pouch at a time or even by the case at the pool store.

I had a green pool, I vacuumed to waste and normally I would triple or quadruple shock at this point. I used 9 pounds at first, the water was not clear after 2 days but cloudy white, could not see to the bottom. I vacuumed to waste again. With chlorine in the pool each day, PH in check, the pool never ended up clearing. The pool turned green once again within a week. This time I added 12 pounds of this shock. My pool is a large oval so I keep continuous chlorine in it. I still can not see the bottom, but it has not turned green again. I will be only using the remainder of this shock as a preventative.

I use the Sam's shock because it was a good value in the past. I really don't think it is a great value, but I was at Sam’s and I needed to shock my pool, so I bought it for convenience. Would I tell someone else to buy it? Not if they could get any other shock on sale.

I have a large custom in-ground pool, recently built with pebbletec lining. I use Sam's club chlorine shock as it is a very good price, dissolves quickly and works very well. I recommend this product to anyone considering it ad it helps to bring down the maintenance cost of your pool and works very well.

Member's Mark Quick Dissolving Shock Stablizer is a quality chlorine product to economically maintain pool clarity. I relied on this product for the last few years. This pool shock provides consistently clear water results when the product is added to keep the pool chlorine level within normal effective algae killing range. But do note it is also important to add an algicide product weekly (also sold by Sam's) to pool as directed to prevent algea overgrowth during extra hot days or rain.

Works as advertised! Seems like a decent value. Ordered online and it was here in @48 hrs. or less and for free, that’s always a bonus! It’s been hard to find in club but maybe that’s b/c it’s a seasonal product so ordering online is a great solution for us!

Very good price for the amount of product.

Iv been using this for years , it does a good job

Cost-effective way to shock your pool. Arrived quickly.
