Features 5

  • Maintain total alkalinity in the range of 60 to 120
  • 11 ounces raises alkalinity 10 ppm per 5,000 gallons of water

Description

This product raises the total alkalinity in swimming pool water. It boosts the effectiveness of your pool water disinfectant, as well as aids in the prevention of scale formation, metal corrosion and the etching of pool surfaces. It helps maintain your pool’s pH level and eliminates pH “bounce”. Easy to use and dissolves quickly. Test for total alkalinity with a reliable test kit. The desired range for total alkalinity is as follows: Fiberglass Pools 70-100 ppm, Marcite, Painted, Tile, or Exposed Aggregate Pools 80-120 ppm, Vinyl Pools 120-140 ppm. If the total alkalinity is less than this desired range, add this product directly to the pool water while the pump is in operation, in accordance with the included table.

Brought my alkalinity up as promissed
Size: 10-Pounds (Bucket)
What can you say here about pool chemicals? I cant do a lab analysis, but I can tell you my alkalinity levels were low so I added some of this and it brought the level up as expected. Good price, but really not any better than the big online pool guys - however it does ship and arrive a whole lot faster than them! ... show more

pool chemical
Size: 20-Pounds
not as inexpensive as I had hoped for but as long as I was patient, I did not have to drive to pick it up some 45 minutes away from our home

Value priced
Size: 50-Pounds
The price was great! Unfortunately, it was 50 pounds of pool chemicals in two plastic bags in a box! NO BUCKET! NO CONTAINER AT ALL! That's why only 3 stars. I had to find a closed container to hold, and protect, 50 pounds of pool chemicals! Not happy about that.
