SpaChoice 2-Pounds 4-Pack Premium Re-Energize, Non Chlorine Pool Shock, Made in USA

This worked great on our spa. The water cleared up and stayed clear. It does not cause foam like some other products and is safer for the spa.

5/5 for a product that is meant to do its job. ith a hot tub in the backyard, we need chemicals like this to make sure our water is balanced. This review is simple as it is a good product. It dissolves quickly and keep the hot tub free of algae.

Like a lot of hot tub owners, I was constantly battling cloudy water. That ended when I discovered this particularly chemical. The first batch I got was a different brand from WalMart but as the summer ended they ran out and I picked this up from Amazon. It was cheaper per ounce than WalMart and is the same chemical. Unfortunately, there are no tests available for its concentration in your water but after discussions with two different companies I concluded that it is safe to simply dose your tub once a week. In between, make CERTAIN you keep your pH where its supposed to be: 7.2 - 7.5. This is a the lower end of the typical given range but it is necessary to keep this stuff working. And when its working it's BLOODY PERFECT. Crystalline, no-smell, no-foam water day after day after day. Mind you that this stuff does not do regular sanitation. You will still need to add chlorine to your water, but without also relying on chlorine to shock your system, the levels can be kept just about to the minimum of their range. I highly recommend this stuff and am confident you'll be happy with the results.

I’ve used a lot of products, but I like this one the best kept my water clear no funny smell will buy again

Keep my spa really clean

Works just as good as the other brand we used

Used half container for 10,000 gallon pool, and was completely surprised to see our slightly yellow pool water turn sparkling clear in less than an hour. Should have taken pictures. Next time will. Always had sparkling water. Running pump, algaecide, bleach. None were needed, pool was clean but water was yellowish. When back washed sand not much till this product.
