I have a 9 seater hot tub and use well water. Added chemicals as per dealers instructions. Water balanced but started looking like pea soup. I added the CuLator Spa pack to the hot tub. I reduced the amount of chemicals. I was using bromine tablets. I was going to drain tub but decided to wait a bit. Within 6 weeks the water was no longer green. Thank you.

We live in an area with very hard water. Our spa water turned green, but it was still clear. Definitely not algae. I looked up the cause and this solution was recommended. When we drained, cleaned and refilled the tub, I added this to the spa. The water remains clean and clear. (Of course, I still have to chlorinate, check pH and all that stuff, but this is a good addition to our maintenance routine.

This product is awesome! I got it last year as freebie or offered a discounted price to try. I did, and am so impressed! I fill my hot tub with well water that has very high iron. The water has a definite yellow tint. Instead of having to dump a large quantity of liquid metal remover product, I simply throw this is and boom! The water is clear! I definitely recommend this product to anyone that has hard water and is on the fence about purchasing. It is worth every penny.

Wish I would have ordered 2!

It is absolutely the best. It lasts 6 months just as described and the water is crystal clear. I have been using CuLator for two years now. Prior I was pouring bottle after bottle of stain and mineral remover into the hot tub.
