Aqua Chem 12101AQU-02 Xtra Blue Swimming Pool Shock, 10-Pack

We started purchasing this shock when it was carried by KMart, years ago. After Kmart closed, had to switch to different brand from Clorox. We use this shock weekly, and use chorine tablets in the skimmer. Never, never have a problem with low levels, or algae. We use a solar blanket, but only occasionally, mostly in beginning weeks of summer when nights get cooler. We do not have a pool heater.Best shock!

I love this stuff! In South Florida (because of the heat), it doesn’t take long for a pool to start turning green, and with the Aqua Chem it starts to work immediately! During “off season” I can “maintain “ the pool by putting in one bag every 3-4 weeks and during the hottest of summer months, a bag every 2 weeks (and turn the pump on for a few hours). The price is reasonable, too.

I've read everyone's review and went ahead an bought this product. Ordered 10lbs. Figuring out after opening my pool they only shipped 5lbs. I'm on my third 1lb shock and it hasn't done anything!!! So poor review, I first get ripped off on the purchase and now product. Sticking with liquid shock.. lessened learned!

We've been purchasing this brand of chlorine shock for nearly a decade and have been getting it on Amazon ever since Walmart starting carrying the cheap Clorox brand instead. That Clorox stuff is useless but Xtra Blue is awesome. It keeps the water crystal clear, like no other product we've ever tried. We won't use any other shock in our pool.

You only get what you pay for. This is the best shock for your money. Keeps my water sparkling. Worth the money.

This product worked great and was gonna buy but it again but the price doubled so bought it else wheres

I only use Aqua Chem for my pool.It dissolves easily after just broadcasting.No preparation necessary. I won't use any other product!

Only product I use
