We will start testing pools for Calcium Hardness on September 25. If the test results show a high level of calcium we will be in contact with you. You may receive an email, phone call or letter to ask you to get in touch with Poolman regarding draining your pool.

The only way to lower the calcium hardness in your pool is to completely drain refill it. Once the pool is refilled the chemicals will need to be reformed. If you use a saltwater chlorinator, salt will have to be added back into the pool once it has been refilled.

We’ve compiled some frequently asked questions about calcium hardness testing to make the process easier to understand.

Q: How did I get the calcium in my pool?

A: Typically, there is calcium already in the water coming out of the tap/hose, etc. Your pool requires a certain amount of calcium. When your pool is first filled with water here in the valley, the calcium level is within range. Water evaporates from your pool year round. Unfortunately, evaporation doesn’t take the calcium with it. As the water evaporates, new water is added to your pool either through the automatic water leveler or by hand using your hose. As new water is added, more calcium is added and your calcium reading goes up.

Q: Isn’t there some chemical you can use to treat it?

A: Unfortunately, no. The only way to get rid of the calcium is to completely drain it and refill it. Your pool should be drained when your calcium hardness reaches or goes over 700 ppm.

Q: How much is it going to cost me to drain my pool?

A; We can drain and reform the chemicals in your pool for just $135.00. (plus $9.00 per bag for salt if you use a saltwater chlorinator).

Our calcium hardness testing occurs ONLY for our Phoenix Poolman customers.
