Ideal for maintaining alkalinity levels between 80-120ppm. ## 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. Review: Works on increasing the ALK levels. - Works well for increasing the Alkalinity of the water. After a big storm where I drained a lot of water, I found my ALK levels being below 50, and I just ran out of the box I got from the local pool supply store. I ordered this, and it arrived in 2x10lb bags and 1x 5lb bag. The way it instructs you to cut makes it easy to pour and the size factor good for most folks to hold. It seems to dissolve right away and raise the Alkalinity as the package states. Advantage with the bags is that it shouldn't leak like a big box with a thin plastic bag. The bags also use a zip-lock type action to keep it sealed until next use. Review: Quality product. - Quality product that did the job at affordable price. ## Features - Sodium bicarbonate for pools - Raises total alkalinity and helps keep pool water pH stable - Maintain total alkalinity in the range of 60 to 120 - 11 ounces raises alkalinity 10 ppm per 5,000 gallons of water - Prevents equipment corrosion and plaster damage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07B81K4XR | | Best Sellers Rank | #15,661 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #62 in Swimming Pool Balancers | | Brand | Pool Mate | | Brand Name | Pool Mate | | Customer Reviews | 4.6 out of 5 stars 1,925 Reviews | | Global Trade Identification Number | 00676215222584 | | Included Components | Pool Alkalinity Increaser | | Item Form | Granules | | Item Type Name | for Swimming Pools | | Item Weight | 25 Pounds | | Manufacturer | Pool Mate | | Manufacturer Part Number | 1-2257B | | Model Number | 1-2257B | | Number of Items | 1 | | Product Benefits | Alkalinity Increaser | | UPC | 034261216139 676215222584 | | Unit Count | 400.0 Ounce | ## Images ![Pool Mate 25-Pounds Premium Alkalinity Increaser for Swimming Pools, 100% Sodium Bicarbonate - Image 1](https://m.media-amazon.com/images/I/71pWIK26uLL.jpg) ![Pool Mate 25-Pounds Premium Alkalinity Increaser for Swimming Pools, 100% Sodium Bicarbonate - Image 2](https://m.media-amazon.com/images/I/71-dZDu15QL.jpg) ![Pool Mate 25-Pounds Premium Alkalinity Increaser for Swimming Pools, 100% Sodium Bicarbonate - Image 3](https://m.media-amazon.com/images/I/71CTQis7MgL.jpg) ![Pool Mate 25-Pounds Premium Alkalinity Increaser for Swimming Pools, 100% Sodium Bicarbonate - Image 4](https://m.media-amazon.com/images/I/71FsLQsRx3L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works on increasing the ALK levels. *by K***N on October 18, 2024* Works well for increasing the Alkalinity of the water.
