Works great and easy to use
Easy to use! Simply open the packet and pour out the liquid. Water is crystal clear! Makes maintaining my hot tub easy. I thought it was going to be powder so I was surprised when it was liquid.

Wonderful product
I thought I was going to have to drain and refill my hot tub. We got this and thought I’d give it a try to see if it would work to clear up the musty stale old bromine smell. I filled the tub (topped it off with water) cleaned the filter then added a package of this. Within seconds the musty smell was gone and the tub was crystal clear. Glad I bought this stuff and tried it. Should last another month before we need to do a full water change now. In the dead of winter this means a lot!!!

Crystal clear
I use this weekly to keep my hot tub clear and it really works. Before owning a hot tub I didn't realize the complication of water balance. These packets make it so much easier!! Glad we discovered them.

Expensive stuff
More suitable for the portable hot tubs, this treats one week in a large hot tub. Not a good value for and 8 person or larger. The seller is very good though.

IT WORKS! ☺️
I have a 4 person Saluspa inflatable Hot Tub. I have had a few of them throughout the past few years and I can say %100 this stuff is hands down the absolute best stuff you can possible use for a Hot Tub to keep it perfectly clean and clear! I pour one lil ounce in once a week along with a small Bromine tablet that floats around. The water has never been more clean and clear. I will literally only use this stuff forever now.

I bought these because I liked the idea of the pre measured packets. Unfortunately I don’t notice a difference in the clarity of my water at all when I use them. I have an actual bottle of clarifier and it is much more efficient. Probably wouldn’t buy again.

Ok when proceed in$30s but over that is crazy.

The product did balance the chemical levels, but it made the water murky after a day or two. I had to add in clarifier and it took 3 days to get it back to clear water. I'll just stick to my basket of pool chemicals and balance them myself....
