One of the most popular questions we get asked is, “How Quickly Does Calcium Rise In A Swimming Pool?” It is definitely a harder question to answer because it truly depends on where you live. We say that because in many states each city has a different water source and it can definitely cause different Calcium Hardness and Total Dissolved Solids (TDS)┬áLevels. Just the other day we had a conversation with one of our Service Providers in Arizona and some cities water comes out at 300 parts per million (ppm) whereas others come out of the tap at 450ppm and higher! Even though that can be common we want to talk to you about a recent pool we recycled because the Calcium Hardness rose pretty quickly. Keep in mind, all of this can change due to the amount of evaporation, where you live, how much shade you have over your pool, and how much you swim etc.

Back in June, we were called out to an 18,000-gallon swimming pool that is pictured above that had 860ppm Calcium Hardness and 4800ppm TDS. After filtering this swimming pool using our Reverse Osmosis (RO) mobile filtration trailer for 14 hours we were able to lower Calcium Hardness to 160ppm and their TDS to 820ppm. This swimming pool is located in Escondido, California. Just six months later, the Calcium Hardness rose to 520ppm and the TDS was 3200ppm. With results like this there are a few things that can be determined:

  • Our water is extremely hard
  • There was a lot of evaporation
  • Puripool service should be performed every 1-2 years

In the end, if you want to keep your swimming pool looking great using Reverse Osmosis filtration is the only option. By utilizing this type of filtration it can bring the Calcium Hardness in your swimming pool to levels much lower than tap, it can prevent damage to your interior finish because we don’t drain the swimming pool and it will give you and your family the best water quality to swim in. This service can be performed 365 days a year, on any surface, to both chlorine and salt pools and is optimal for both residential and commercial swimming pools. High levels of Calcium Hardness in your swimming pool can cause damage to your tile, interior finish, filtration equipment, and salt chlorinator if left untreated. Utilizing this service can not only prolong the lifespan on your swimming pool but also give you the best water quality to swim in. If you’re curious to know more, contact us today!
