About this item

  • Why Maintain Hot Tub pH? Did you know that the water in your spa should be maintained at a pH of 7.2 to 7.8 and a total alkalinity of 80 to 140 ppm? Using pH Increaser & Decreaser for spas helps maintain your hot tub chemistry effectively.
  • pH Up & Down For Hot Tub Spa - Our pH Increaser and Decreaser for hot tub kit helps maintain your hot tub chemistry balance. If your spa's pH measure is below its range, use our hot tub pH booster, and if the pH measure is below its range, use our hot tub pH decreaser.
  • Spa pH Increaser & Decreaser For Hot Tub - When your hot tub pH is not at an ideal level, it indicates that your hot tub water is too acidic, and your sanitizer will be less effective. Using Aquadoc's pH Balance Kit also helps balance the total alkalinity level.
  • Adjust pH Levels Effectively - Incorrect pH levels can impact the water quality, imbalance other chemicals, and cause the water to give itchy skin and eyes. Our pH up and down kit also helps deal with it all by treating cloudy tub, scaling build-up, and more.
  • pH Chemicals For Hot Tub Made In The USA - At AquaDoc, we make high-quality spa chemicals to help balance your hot tub and spa chemistry and treat them with care. When you choose AquaDoc, you are getting consistent quality.

Got this duo for my hot tub. Seems to work just fine at balancing the Ph in my hot tub. One of the bottles was leaking from the lid not being on properly but of course, that’s more of a packaging issue. Great product and does the job as needed!

I ordered these when we were having some PH problems with our swim spa. Of course when they arrived the challenge had been resolved and so it took a while before I needed to try them. We did get a high PH reading and used the spa down, it worked great. I like that they have left out certain unsafe additives. I also like that they support the Wounded Warrior Project, which my brother in-law has been a part of and has helped many people. I like supporting products that give back. These cost a bit less than what i was previously using which is always a win these days.

AquaDoc is a newer brand to me, but I’ve been impressed with their spa and pool maintenance products, and this pH increaser is no exception. It works very effectively, balancing pH levels quickly and reliably, which makes maintaining water chemistry a breeze.One thing that stands out to me is AquaDoc’s commitment to USA-made products and their support for the Wounded Warrior Project. As a former member of the Army National Guard, I really appreciate seeing a company take pride in supporting our servicemen and women, which makes me more inclined to support them in return.I haven’t had to use a pH decreaser yet since my water typically runs on the lower side, but the pH increaser has worked flawlessly every time I’ve used it. Another plus is the size of the bottles - they’re much larger than I expected, which is great for long-term use.Overall, this is a dependable option for spa and pool owners who want effective results and value supporting a good cause.

oh increased didn’t work. Too expensive and had to use a whole bottle for my spa and it only took it up by from 6.9 to 7.0. Had to express the chlorox powder ph-up and only added a little and took it up right were it needed and it was cheaper this crap. Only 4% of the active ingredient is in this product. Waste of money.

These are a must for the spa owner. They work well to restore balance if used according to the instructions and in the correct amounts. The set seems like a good way to purchase.
