SpaGuard Enhanced Shock (2 lb)

New to owning a hot tub. I had green tinted water for about 2 weeks. I tried everything to get it to go away. Nothing worked. So I bought this stuff. It was clearer within hours and crystal clear the next day! Will be using it like other reviews said and adding a table spoon every week.

Yes! just as effective as other brands at a good price, we have a ot tub, and did a lot of reaseard on supplies etc...all companies have told us do not use anything clorox brand in your spa! This one measures up and fits the bill.Great product and fast delivery.

Good price and it works well, but all pool products from the pool store are always much higher priced for the same thing. That's why you stick with amazon.

Seems too work well. Only used once..

A lot of dazzling names out there but it’s the chemical composition that is nearly identical in all these shock products, so ignore the names and check the active ingredients. We use the frog system, but their shock is outrageously expensive on a per oz basis. Plus this stuff has a higher percentage of the active ingredient. For our small spa, I use about 1 oz once every week or two and it’s been keeping the water pristine. The frog system is pretty simple and does well, maybe a bit more cost but takes little attention. I find a bit of chlorine based shock and a bit of calcium for hardness control periodically keep our spa water well controlled. Looking at a handful of competing products this was the most cost effective at the time.

I love this stuffWe use to use Leslie’s and it was constantly adding chemicals to get it right and always had a brown line on water line in certain parts of tub but since using this product less than the other it cleared it up and not adding other stuff to get it right. This is a great product Good Job guys🇺🇸

I have ordered this product for our spa several times through Amazon. It keeps the water clean and prevents buildup. It’s an effective and an easy to use solution to maintain clean spa water. Love the convenience of having it delivered to my front door.

2nd purchase of this. Works great
