Works, but Needs Higher Dosage Than Recommended
The AquaDoc Alkalinity Booster does the job, but I've found that I need to use more than the recommended amount to see noticeable results in my hot tub. It does help balance the alkalinity effectively; however, it would be great if the suggested dosage was a bit more accurate for quicker results. Overall, it’s effective, but be prepared to adjust the amount based on your needs.

This Stuff Works!
I was having trouble maintaining the pH in our hot tub with the 3-in-1 balancers, so I tried this stuff. You don't have to add very much and within 30 minutes, your pH is fixed! I would definitely recommend this 10/10.
