Can this product be used in a pool to lower the Ph?

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.

Can you use on glass showers?

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

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!

The best product for shower doors is: https://www.amazon.com/Shower-Hard-Water-Stain-Remover/dp/B00WNAJAG0?ref_=ast_bbp_dp

Will this work on windows that have 20 years worth of hard water spots? i'm not afraid of the work but i have used everything else and nothing works.

Excellent sea shell cleaner!!!

This solution is absolutely amazing at dissolving the calcium film on shells. There is no harsh smell, and ACID Magic is not dangerous/caustic like Muriatic acid. I love using it and I feel safe doing so.
