You need to maintain your pool water pH levels and total alkalinity for the comfort and safety of users and for other pool products to work properly. Use test strips or test kit to measure ph. The ideal pH for pool water is between 7.2 And 7.6. Follow dosage chart on CLOROX Pool&Spa pH Down to adjust pH as needed.

This stuff sucks! I normally only use HTH brand pH reducer and it works excellent!! However, it is $20 for a 7 lb bottle so I decided to give this stuff a try. It is nowhere near as good as the other dry acid products I have used. My pool is only 7000 gallons and I added the correct dose. The pH came down from 7.7 to 7.5 after two hours then shot back up to 7.7 the next morning! My goal was to get the pH down to 7.3-7.4 range, which never happened. My alkalinity is 80 which is perfect for a pool my size so the pH should be somewhat stabilized. This stuff is much better suited for spas/hot tubs, not medium to large pools! I’m sure it’s great for kiddie pools, though.
Buy muriatic acid if you are not afraid of it like I am. If you prefer dry acid, spend the extra money on other pH Down products. HTH pH Decreaser works awesome! This stuff is for tiny pools or hot tubs only. I only gave it 2 stars because it did bring my pH down a tiny bit and it is easy to pour.
****EDIT 9/26/19: I did not realize this product is dosed differently than my other stuff. It actually DOES work in my 7000 gallon above ground pool, just not as quickly. I’ll keep buying HTH brand but this stuff does work. Bumped my rating up to 4 stars instead of 2!!****
