Waters Choice Pure Enzymes for Spas Hot Tub Enzyme Cleaner & Spa Water Clarifier – Chemical-Free Hot Tub Cleaner, Spa Enzyme Treatment for Crystal Clear Water, No Harsh Chemicals

We've had a hot tub for over 2 years now in Portland, OR. We started out using the Leisure Time products recommended by the hot tub retailer. This included chlorine, spa "up", spa "down", "shock", calcium and occasional use of a defoaming product. We had to use a lot of chemicals to keep the water balanced and clean.Our hot tub dealer mentioned Waters Choice as an alternative that used a natural enzyme and would require less chemicals. We slowly transitioned over, and now have been on Water's choice for over a year now. It's nearly impossible to review these products individually since they are part of a water maintenance system. Thus, I'm really reviewing this product the Water Choice system of which this product is a part.PROS:1. We definitely use less chemicals and save money. Usually, we need to add a little bit of chlorine every few uses. Sometimes we need a little "spa down" to decrease the PH. We add a capful of the enzyme every 2 weeks and our water stays really nice! No more shock, calcium or defoamer products needed.2. We only have to change the water every 6 months to 9 months. Our water wouldn't stay nice as long with the old products.3. This is definitively subjective, but the water just FEELS cleaner and nicer. It doesn't get the odor is would occasionally get using the old products.CONS:1. I feel their instructions could be a little more clear and consistent. For example, they could consistently provide measurements in terms of "capfuls" instead of ounces, tablespoons, teaspoons, etc. It's a lot easier for most of us to measure out 1/4 or 1/3 capful rather than 2 oz or 2 tablespoons.Give it a try for yourself!

After many many years of trying countless products and systems to manage our spa sanitation without success, dumping loads of chemicals into the water just to get it normalized, constantly testing using a zillion testing strips, battling slime, stink and foam and most of all suffering from skin irritation from all the chemicals we found this system and it works. It so freaking works! It’s so simple yet innovative. Highly recommend. Follow the instructions and you’ll find success and a clear comfortable spa experience.

I've been using this for about 4 years. I keep my water balanced; alk 90, chlorine at 3 ppm, ph 7.6, hardness 250 ppm and I have an UV/Ozone system. When I don't use the enzyme, the water develops a smell faster and it eats more chlorine. When I do use this enzyme, the water feels softer and never gets a scum line and never smells. My tub is 400 gallons and I find i need to water change every 3 or 4 months because I do get cyanuric acid levels over 120 after 3 months which is a result of chlorine usage. I tried to keep chlorine at 1ppm, but my water will get nasty fast at that low level. I think it is because we have some frogs when chlorine is low. Great product, I keep buying it.

We are using the same product that was sold to us when we bought the hottub. The product hopefully is doing what they say.

This product worked just as described. I have been using it and reordering for almost a year and have been copletely satisfied. I have also turned my friend onto it and now they use it regularly too. The water stays fresh and clean with no smell. I use one bottle per month even in the months when I have visitors.

I have used this product for a year and a half since we first purchased our hot tub, as a start-up kit of this product came with it. The water has always been clear. I only need to put a small scoop of sanitizer (spa chlorine) in after every other use. There are also some nice scented salts made by this company that you can get for aromatherapy, if you desire. I have used the “wellness” one that has a eucalyptus scent…a nice occasional treat. My daughter swears that it opens her sinuses.

Ordered for my parents, they loved them. I will continue to buy this brand!

Fantastic product. We try to keep our hot tub chemical free and this does the trick. These enzymes kill the proteins in the water, making it crystal clear and easy on the skin. We have kids that use the hot tub a lot, so we decided the chlorine free route. These bad boys keep up with the job well.
