Calcium scaling on decorative tile

Have you ever walked into a pool store and they told you your pool water is too hard? Do you even know what that is referring to? In the swimming pool industry, calcium hardness and total dissolved solids (TDS) are what the swimming pool industry refers to when they tell you your pool water is hard. This is going to happen to you and we want to use this blog post to educate you on the steps you need to take to prevent it from happening. First and foremost, our tap water is loaded with calcium and other hardness minerals which make it hard. Most homeowners are familiar with this because it scales their shower heads, cars, windows, and faucets. But have you ever thought about what it is doing to your swimming pool? It is actually a much bigger problem and most swimming pool owners are not familiar with what they are.

Calcium is in our tap water and as the water in your swimming pool evaporates the calcium and other hardness minerals remain in solution and gradually build up in concentration. When this happens, the calcium will scale your tile, interior finish, filtration equipment, decorative water features, and spillways. It literally destroys your swimming pool and is invisible to the naked eye until scaling occurs. Once this happens, it begins to take life off your swimming pool and can be extremely expensive to remove if you choose to go that route. One thing we forgot to mention is if you have a salt water chlorinator, high levels of calcium can make it nonfunctional. So this leads us to the question, how do I remove the hard water in my swimming pool?

When this happens, you have two options….. You can perform a drain and refill which is extremely dangerous when temperatures are above 80 degrees and only fills the pool up again with hard water or choose to recycle the water instead. At Clark County Pool & Lawn we offer Reverse Osmosis (RO) mobile filtration that comes to your residential swimming pool and recycles the water on site. RO filtration will lower the following issues:

  • Calcium Hardness
  • TDS
  • Cyanuric Acid (CYA)
  • Phosphates
  • Salts
  • Waterborne Diseases

This process conserves up to 85% of the existing water in the swimming pool and doesn’t expose the interior finish of the swimming pool. Since we use RO filtration we are able to bring your water down to calcium levels far below tap water. This is actually the best quality water you and your family can swim in. Not to mention, if you choose to use our process every two years (or sooner for salt pools) you can prevent excess calcium scaling from occurring.
