## Questions & Answers

**Q: Can this product be used in a pool to lower the Ph?**
A: Ive used a few teaspoons for my 215 gallon ozone hot tub to lower ph without affecting the alkalinity and then I neutralize it with maybe an ounce of baking soda and for alkalinity adjustments but I haven't seen any green water from this. Ill keep an eye on it. And keep everyone updated.

**Q: Can you use on glass showers?**
A: That is still acid and dangerous, I use a product I found in the pool store for cleaning fiberglass hot tubs from hard water, spots "DeScale it", still a chemical but you spray it on the glass let it sit a few minutes to become super soft and then take type of scrub sponge wash it right off - Although I buy it much cheaper https://www.amazon.com/Descale-It-Bathroom-Cleaner/dp/B00170DANG/ref=sr_1_3?crid=2PQ67MVFD2X0W&keywords=descale+it&qid=1689714002&sprefix=descale+it%2Caps%2C153&sr=8-3

**Q: Will this work on windows with 15 years of hard water spots?  i have tried everything- no joke.  i'm desperate for something even caustic chemicals!**
