Product details

Pool Season calcium increaser is 100 percent calcium chloride in granular form, supplied here in an 8 lb pouch. It does one job: it raises the calcium hardness of the water.

Why hardness matters

Calcium hardness is the third reading in the balance set, alongside pH and total alkalinity, and it is the one most often left alone. Water that is short on calcium does not stay short. It takes calcium from the nearest source, which is your plaster, your grout, your tile line and your metal fittings. Etched surfaces, crumbling grout and corroded equipment are the visible end of that process.

Using it

Test first, then dose from the label directions for your pool volume and your current reading. Because this is a granular balancer, it goes in, circulates and is retested rather than being added on a schedule. Getting hardness into range also makes staining less likely, since balanced water is far less inclined to mark the pool.

Questions and answers

What people ask about this product, answered by our pool techs.

What does calcium increaser actually do?
It raises calcium hardness. Water that is short on calcium will pull it out of whatever it touches, which shows up as etched plaster, eaten grout and corroded metal.
Is this the same as an alkalinity or pH product?
No. Calcium hardness is a separate reading from pH and total alkalinity, and this product moves only hardness. Test for all three and treat them in the order your test kit recommends.
How much do I add?
That depends on your pool volume and how far your current hardness reading is from the target, so dose from the label directions and your own test result rather than by guess.
What size is this listing?
The 8 lb pouch. Pool Season offers this product in other sizes as well, so check the size on the listing before you order.
