SPA FROG Maintain Non-Chlorine Maintenance Shock Single Use Packets 12-Pack with Bonus Hot Tub Water Balancing Guide

Does what it’s suppose to do. I use one packet every week and keeps our spa crystal clear!

I was looking forward to receiving the hot tub water Balancing Guide but didn't!

I use the FROG ball device.. they last about 3 weeks on setting 1 in a 260 gallon Hot Tub.The Frog Ball does keep the water crystal Clear... and very light chlorine smell.. . but not cheap. I do use regular Chlorine shock once in a while.... to be safe. 2 months and only once, green water. Not sure how these packages work exactly.. used two of them over two months.. no issues.. no smell. (one package broke open but was OK... did not loose any chemical.Frog systems not the cheapest but they do the job and super easy to use. Does cost $$$ and the bottom of the Ball is tossed (more plastic waste .. SAD). Nice if you could refill the balls with their compound.... the top blue part lasts about 6 months (Silver disk inside?)

No more multiple chemical doses and testing. This one packet used weekly does the job and Hot Tub water stays ready for use all week. Combined with the Frog@Ease system and I've never had a problem with the water in my Hot Tub.

I’ve been having trouble for a couple months with getting chemicals right. Bought the floater and shock in this brand and easy thing we’ve found that really works

Easy to use. Keeps our hot tub water sparkling. Love it. Great price for what it does!!

One packet doesn't completely do the job but might be the size of the hot tub.

Stuff works good but don’t expect it to be nicely packed in a box apparently. So only 3 stars
