Reverse Osmosis For Swimming Pool Water

If you own a pool in our area you’re going to need to change the water in your swimming pool every two years. As a residential and commercial swimming pool owner in the Orange County area, you are going to have to deal with high levels of Calcium Hardness (CH) coming out of your tap/fill water. Since this is present in our tap water it is important that you familiarize yourself with all the reasons why keeping your CH within normal levels will help keep your pool looking great. If you talk to most pool professionals and look online the average recommended levels of calcium in your swimming pool will be between 200-400 parts per million (ppm). Unfortunately, in the Los Angeles area, the hardness levels coming out of the tap averages 400ppm. So what does that mean as a swimming pool owner? The simple answer is damage to your swimming pool and filtration equipment but it’s so much more and we hope this blog post helps you understand why keeping your calcium levels lower will make your life much easier!

First and foremost, your swimming pool will need to have some calcium in the water to keep the integrity of the interior finish intact. But, you will want to make sure that it’s not too soft (below 100 ppm) or too hard (over 600 ppm) because this is where problems occur. When dealing with calcium levels below 100ppm the water will be too soft and it will cause long-term serious damage especially to the interior finish (plaster), vinyl liners, grout in between tiles, metal rails, and even concrete decking around the pool. It does this because it is very aggressive and it actually seeks to dissolve and bring into solution minerals, metals, and other substances. Although soft water is desirable in everyday home use, calcium hardness is necessary for pool water.

Whereas, when calcium levels climb above 600ppm the calcium will scale the interior finish, water tile line, filtration equipment, decking, spillways, metal rails, salt chlorinators, and decorative water features. When scaling occurs, it can be tough to look at and it can make it more challenging to take care of your swimming pool which means it must be lowered. At Pool Water Recycling we recommend Reverse Osmosis (RO) filtration because it can give you better water than tap, there’s no downtime during filtration and it conserves up to 85% of the existing water in the swimming pool. You will notice a difference in the feel of the water as well as the quality too. If you should have any questions on how this service works, please contact us today with any questions.
