AquaDoc Spa Enzyme Water Treatment - 16oz - Natural Hot Tub Enzyme Cleaner & Clarifier for Balanced Water - Made in USA

I ended up buying this natural enzyme as it did not come in the kit from the same brand. It works great and really ensures that your hot tub remains clean from soap and natural oils on our bodies and clothing. This is a great value for the money and has been lasting me a few months per bottle. This does not dye the water or give it any type of color that would be off from clear. There is no smell to the chemical. Overall, this brand is very good for our inflatable hot tub and I will be purchasing whatever is needed to maintain from them again

Works great, simplifies treating hot tub

Worked well to remove scum line when used as directed. Did manually clean the waterline after a week of use to ensure all was clean, but the enzyme did the bulk of the work.

Works for clearing up cloudy water & scum

Great for my 18ft swimspa. Filters stay cleaner. Very minimal to no scum line saves on chemicals. With balanced chemicals stays clear for a week covered

I use the entire Aquadoc line of products in my bromine based hot tub. I especially love the chemical dipsticks because the color changes are very discernible and make it easy to know you’re in the correct range.

Very good product

A small amount of this product add ed two or three Place hot tub virtually eliminates bathtub ring. We usually let our water go 11 to 12 weeks. This makes that possible.

Seems to have worked well. No nasty smells or discoloration to the water, you'd never know it was in. Very easy to use, seems to keep the water nice and clear alongside normal maintenance. Seems better value than others I looked at.
