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.

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.

I prefer this over the liquid but use both.
