Model # P37010DE
Azure Calcium Hardness Increaser is used to raise calcium hardness in swimming pool water. Low calcium hardness may cause pool water to become corrosive which can result in etched plaster, corrosion of equipment and fixtures or may cause metallic stains. The Ideal range is 200 to 400 parts per million (ppm). The minimum calcium hardness level is 150 ppm.
ACTIVE INGREDIENT:
Sodium Bicarbonate
DIRECTIONS:
1. Determine calcium hardness level. It should be between 150-250 ppm.
2. If the level is below 150 ppm, add Calcium Hardness Increaser by distributing the product over the water surface. 1 lb. of product will increase the calcium hardness 10 ppm in 10,000 gallons of water.*Caution: Do not add more than 10 lbs. per 10,000 gallons of water at one time. If the pool needs more than this, add the 10 lbs./10,000 gallons amount then retest 12 hours later. After testing, you can make the necessary adjustments.

Never added calcium hardness increase but this product has successfully balanced my water more so than in any other season. Will need an additional 5-10 lbs to get my hardness into normal range. Shipped fast. Recommend.

(5 out of 5 stars) Hardness Increaser Does the Job
Reviewed By: lakeside_tony from Cumming, GA ()
Pros: Works great, great price, fast ship.
Cons: Lid came off first 2 shipped.
This is great hardness increaser at a great price. Only issue was the lid came off during shipping.... and on the reship too. However, to their credit, Inyo worked great with me and their vendor to get it right and the third time it came taped and sealed so the lid couldn't come off. Hopefully, this shouldn't be a problem anymore. Thanks Inyo !!
