Pool Mate Calcium Plus is used to raise calcium hardness levels when measures drop below the recommended range of 200-400 ppm. If calcium hardness levels are too low the "soft water" will corrode pool equipment, etch pool plaster and may cause metallic stains. This is a dry granular product that increases the total hardness in pool water to the recommended range. Directions for use: Test for calcium hardness with a reliable test kit.The desired range for calcium hardness is as follows: Vinyl Pools - 200-300 ppm. Tile and Exposed Aggregate Pools - 200-400 ppm. Marcite, Fiberglass or Painted Pools - 250-400 ppm. If the calcium hardness tests less than the desired range, add this product according to the guide below. Place this product into a plastic bucket already filled with swimming pool water. Do this in a ration of up to 2 pounds of product per approximate 5-gallon bucket of water. Slowly pour this solution around the perimeter of the swimming pool while the circulating system is operating. In a 10,000 gallon pool, do not add more than 10 pounds of this product per 2 hour period. For 5,000 gallon pool: to increase by 10 ppm add 7.2 oz., to increase by 20 ppm add 14.4 oz., to increase by 30 ppm add 1.35 lbs., to increase by 40 ppm add 1.8 lbs., to increase by 60 ppm add 2.7 lbs., to increase by 80 ppm add 3.6 lbs., to increase by 100 ppm add 4.5 lbs.

Works!
Brought levels up in Saltwater pool in less that three days. Put in sock in skimmer baskets and dissolved with no issues.

This Stuff is Legit
I was shocked to read some reviewers say this wasn't pure or weaker than other like products. That's patently false. This stuff is legit. I poured 5 lbs in a 5 gallon bucket (half filled with water) to start with and it got way hotter than expected. It dissolved much easier and in the next minute while pouring it around the perimeter of the pool, the bottom of the bucket nearly got too hot to touch. I couldn't believe the heat coming off of it. It raised hardness quicker than expected and I couldn't be happier. Fantastic product at a great price.
