If I could give the product more then five stars I would.
First, I would like to share that I am not affiliated with The Natural Hot Tub Company or receiving any compensation for my review. I have had a hot tub for 30+ years and have had unsatisfactory results with chlorine, bromine and another natural water treatment product. Chlorine and bromine were hard on my hot tub and cover, Even though I tested the water weekly, I had trouble keeping the chemicals in balance. I always ended up with chemical odors and a tub that was hard to clean. I tried another natural product that left sticky water level rings around the tub. The Natural Hot Tub Company products have eliminated all of the unhappy results that I have dealt with for years. I have been using this system for a year now and I love it! With this system, I don't have to test my water. All I do is add a small amount of shock once a week, add the prescribed amount of water treatment every three months and clean my filter once a month. The water is always clear, odor free and soft on my skin. I recently drained and cleaned my tub for the first time in about year and there was no residue, water level ring or mold on my tub or cover. I think that the success that I have had with this product is due to following the prescribed process of converting my tub to the new system. You can't just add this product to your existing tub and expect good results. After using this product for about six months, my water became a bit cloudy. I called the company and they recommended that I replace the filter and be sure to run the filter system at least 8 hours a day. Sure enough, that took care of the problem. Now I clean my filter once a month as recommended and have not had a problem with cloudy water since.

Best product for Copper Filtration!
I recently purchased a spa with a copper filtration system. I tried several different products before landing this one. It makes the water soooo soft. Our spa gets daily use and I probably add a cap of oxidizer 1x/ week or less. One bottle does two treatments for our spa. I drain and fill each time I use it, approximately every four months. Best product and works great with the copper filtration!

First not so good then improved
See edit below......Sorry folks but I searched far and wide for an all natural enzyme water treatment for my new outdoor spa. The first thing I did was try to contact The Natural Hotub Company from their website asking how their product would perform with an upgraded Delzone Ozonator I had installed in the spa. I never heard back from them. I thought I would try the product anyway to keep my water clear and PH balanced for the reported 3 month period they said it would work with minimal chemicals besides using new ozonator as the main oxidizer. My water started getting cloudy within 9 days and the PH was already getting lower than 6.8 in that short time period. I also used a high end Unicel filter with the spa. Also I didn't feel the silky smooth water the product was supposed to create. I used a full bottle in a 375 gallon Sundance Altamar Spa which gets used by one person normally 3 nights a week for 30 minutes each time. Spa was only 90 days old and water was already changed once since then for warranty work. I didn't see any benefits beyond purchasing a generic enzyme treatment (e.g. Leisure Time) which is a treat water as needed method. As a matter of fact, the treat water as needed enzyme is significantly less expensive over three month. I won't be purchasing another bottle of The Natural Hot Tub Company Water Treatment and Conditioner. Edit 11/17/23: I am changing my tune on this product. After a couple of weeks my water started to stabilize along with the PH, and the water remained clear with only ozone filtering. I did not need to add chorine and had to shock the water only a couple of times over two and a half months. The water was crystal clear with no other chemical treatments so there was definitely an improvement compared to how much chorine and shock treatments & liquid enzyme I was using prior to using The Natural Hot Tub Company Water Treatment. It naturally decreased tremendously the amount of attention I needed to spend on spa maintenance as well. Due to reoccurring issues with my spa jets, my spa Mfg. is replacing my spa with a new one and I am purchasing another bottle for the new spa. I am not giving it 5 stars because it took a couple of weeks for the product to stabilize and the company did not respond to my inquiries.

Use this and end toxic products.
Use this instead of bromide and chlorine! Your skin and hair will thank you. Another tip: 15 minutes before using your tub add some non-chlorine shocker and run the jets. This two product combo replaces toxic chemicals. I learned this from a manager at Catalina Spas two years ago

The Enzyme Works!
I've been using this product for over 30 years. Seriously got the first time off an ad in the back of Sunset Magazine. It works. We use our spa several times per week. If there is a film from lotions etc., give it a day and it disappears, eaten up by the enzymes. No more itchy skin from chlorine. I am a lifetime user and believer in this product. Just wish it was cheaper. Almost 50 bucks a bottle is pretty steep. But then again, it lasts in our spa 6+ months.

Don’t waste your money
We used the cleaner first, emptied the hot tub and followed all the directions and within three days our water was cloudy and smelled. Then a ring formed around the waterline. We had to go to the spa company and get the proper cleaner and “natural” chemicals. The new cleaner got so much gunk out. We had to empty the tub again and use the correct chemicals. It’s been a week and the water is still perfect. Brought this bottle in and he said lots of people have used this only for to not work. This tells me that this cleaner and water treatment does not work at all. Don’t waste your money! Go to the spa store and get the right stuff!!
