Calcium Removal From Your Pool Water
Interestingly enough, calcium is essential for your pool to keep the interior finish intact but in parts of the United States, like Orange County, there is an issue of having too much calcium in the water. Did you know, in some parts of the country they actually sell calcium because it’s recommended to have no less than 200 parts per million (ppm) in the pool? If that happens it can actually cause issues with the structure of the swimming pool. Whereas, on the west coast the thought of adding calcium to swimming pools is baffling because our fill water is loaded with calcium, magnesium, and other hardness minerals that cause major problems for us.
It’s extremely common to hear how do I get all this excess calcium out of my pool, what is the white line on my tile or why does my pool use so much chlorine? Our fill water is loaded with it. The Grand Canyon is covered with limestone which in turn causes our water to be filled with calcium and other hardness minerals. In Orange County, the hardness in the water can be anywhere from 350 ppm and higher. This issue ends up causing major issues if you own a residential or commercial swimming pool. Calcium actually scales the interior finish, scales the waterline tile, begins to scale the plumbing as well as the pool equipment which actually decreases the life span of them all. As water evaporates in the pool the hardness minerals remain in solution and over time they continue to build up which is why it’s most visible around the water tile line. As calcium builds up it acts like a sponge and sucks up chlorine at a very high rate causing cloudy water, the potential for algae growth or burning eyes and skin due to high chlorine levels to keep the water clear.
The easiest solution to this was to drain the pool and start over. But as was discussed above the water coming out of the tap is already hard. That’s why at Pool Water Recycling, we utilize Reverse Osmosis (RO) mobile filtration to recycle swimming pool water. We are able to actually conserve up to 85% of the existing water in the swimming pool. It’s the perfect alternative to areas in the U.S. where water is at a premium but it also has the following benefits for swimming pool owners:
- Can be completed in less than a day for most residential swimming pools.
- Lowers Calcium Hardness, TDS, and CYA
- No need to rent a pump or call a company to drain the pool
- The water coming back into the swimming pool is drinkable
- The water is softer and better for the hair, skin, and nails.
- Your chemical usage will be less
- Water conservation
- If performed on a regular basis (typically every 2 years) it’s possible to prevent the visible calcium ring
The price of the service is extremely competitive with a drain and refill but again because the water is of better quality it makes your swimming experience much nicer and can really extend the lifespan of the pool.
