CuLator Spa-Pak Hot Tub Metal & Stain Eliminator

I actually dropped this in my toilet tank to decrease the rust staining in the toilet bowl. It worked really well. But you have to remove the rust stains in the bowl first. It doesn't remove the stains but the iron in your water.

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.

This was exactly what I needed for our hot tub.

I fill my spa with well water - high iron content. CuLator packet for a few days prior to adding any chemicals and no bad stuff!! Fill without CuLator and get pea soup.

I have heavy iron in my water for the well. CuLator Hot Tub Metal Eliminator worked well the first time I used it. It took a couple of days to clear the water but it did the job. Now one month later when I added water to replace what had evaporated it is not working so well. It has been about four days and the water is still stained. The reason I gave it four stars and not lower is that no other produce worked at all. So, CuLator works well at first but the claim of 6 months seems to be stretching it a bit.

After trying many other products CuLator cleared my iron stained water It was so simple. Nothing to measure, just dropped it into my skimmer and forget it. I have had it for almost a month and it is still working

This product works! I know I have iron because I fill with well water. I've had problems in the past with staining my fiberglass. I've even had my water turn green after shocking (like the Olympic Diving Pool!). CuLator prevents the staining AND the water turning green. Sometimes, I get a little white stuff on the outside of the bag, but that is just body oils. I use CuLator all the time to keep my spa clean.
