EcoOne Spa Monthly | Gentle All-Natural Spa Treatment | Conditioning Hot Tub, Pool, & Spa Cleaner | Above, In-Ground, or Inflatable Hot Tub Cleaner Stabilizes pH & Alkalinity, 8 Oz, (1-Pack)

This product is fantastic. Our hot tub water is always crystal clear and smells very fresh (not like chemicals). The best part is that all I have to do is put one bottle of this a month in the hot tub (and chlorine tablets only as needed). So, this product makes for a very low maintenance.

Keeps our hot tub balanced and clean.

Since getting the chemicals out of my spa I have gotten rid of all skin rashes and irritation. Switch to enzymes. They really work keeping my spa water free and clear at all times by just using this system. Yes it is as easy as using this bottle once a month after the initial start up. No chemical smells. No cloudy water. Just fresh clean clear water.

I have a wonderful Plug & Play above ground hot tub. It is designed for two people to lounge in and only requires 150 gallons of water. The interior color of the shell is slate gray so the hard water ring became very visible in no time and my skin felt rough. I searched for a spa water softning product selecting this one mainly because it was the right price for me and reviews were good.I was confused reading the directions that instructed using the entire bottle in a 7,000 gal. Spa!! Had to calculate what my little spa needed. I ended up adding about 6 capfuls or so and in a day the water felt soft, smooth, and more relaxing. It didn't create any slippery feeling and the white hard water ring had disappeared! An economical great product for a little tub and there's a lot left for future spa refills.

This is good stuff but a bit expensive. We’ve been using it for years but would really appreciate if it was less expensive.

My skin is sensitive and gets very itchy and dry after hot tub. This makes water soft and helps my skin ALOT! I love this product, ended up ordering 6 pack and put in once a month, it also helps balance other chemicals

A commodity item. Shop based on price.

Great product. Keeps my spa - hot tub's water nice and soft. Reduces the foam effect too.
