Caribbean SpaFast-Dissolving Chlorine-Free Shock Oxidizer for Hot Tubs Presented by Pool Stuff Express (5Lb)

This product keeps my hot tub nice and clean and helps keep my chemicals in balance. It arrived quickly and container was undamaged.

I weighed the bottle when I got it. It weighed 2.4 lbs including the bottle. Bottle was about 3/4+ full, but the full amount of weight was there. This has 45% potassium monopersulfate, where the brand we had previously was 32% potassium monopersulfate. We add sodium bromide as a starter, then the "shock oxidizer" to maintain an oxidant residual.

Works great !

Easy to use , works great.

Good product

Working great

works great.

This stuff is great. But don’t buy it unless you only wanna pay for 75% of the bottle. Will be finding another shock that I will receive the whole product.
