Product notes: Follow label directions/precautions. Not to be used to aid or effect a pool or spa disinfectant or water modifier.
This works great to balance our spa water, which is extremely basic well water. I had so much trouble using the Alkalinity Down-type products as they were entirely ineffective, and I was quite confused as to why my water was still so gross. A few capfulls of this acid does the trick.
This is a suggested product to clean the hot tub filter. It worked. The filter looks like new again
I used it to acid wash so rust stains on the floor of my pool. It did the trick and NO FUMES..
I bought this product to help with reducing the high alkalinity of my well water. It seems to be working and I am finally able to adjust my pH properly. The only issue that I had was that one of the bottles had leaked. The caps were not taped closed and the bottles were laying on their sides, even though there is a warning to ship them upright.
This was the only thing that would drop the alkalinity in my hot tub.
the water in our part of the country is very hard, with high alkalinity and pH. I had been using ""dry acid"" compounds in my spa to lower alkalinity and pH after my last drain and refill. I could NOT get either value into acceptable ranges, and when they were reduced to near acceptable levels, they would only stay there for 2-3 days, then would be high again. Resulting problem...cloudy water. this product was more effective at lowering both alkalinity and pH, and I plan to use this product in the future to treat my spa water when I drain and refill.
Really really effective
Great cleaner for shower tile. Have not found anything better.
