Your pool water is hard which means it has too much calcium, magnesium, and other hardness minerals in it. Pure Water has a solution and we answer some common questions about hard water below:
WHY IS MY POOL WATER “HARD” AND WHY DOES IT GET “HARDER”?
From the day your pool is first filled, it is often above the standards for pool water chemistry in Calcium Hardness (200 to 400 parts per million, or ppm) and continues to increase as you remove water by getting out of the pool, splashing or evaporation. To replenish this lost water, new water is added and additional hard water is introduced; raising the concentration levels of this hard water (predominantly Calcium and Magnesium) and creating a higher level of these minerals. This level increases, creating such hard water that your chemicals can no longer do their job, dictating the need for higher chemical levels to keep the pool safe. Additionally, scale builds on your interior finish, tile, pool plumbing, and equipment, which can lead to failure and expensive repairs!
HOW IS HARD WATER TYPICALLY ADDRESSED?
In the past, the water was dumped down the drain! If the average pool has 20,000 gallons of water and if only 1,000 pool owners (out of the tens of thousands in our area!) dump their water a year, that means 20,000,000 gallons of water is not only wasted, an additional 20,000,000 is needed to refill these pools! Using the very realistic recovery of water with our system (80%), that would mean an annual savings of 32,000,000 gallons of water a year!
I CAN’T SEE THE HARDNESS IN MY POOL; HOW DO YOU KNOW IT’S REALLY THERE?
You may not be able to see it in the water (although we suggest turning your lights on one night and see if you see anything floating around in your pool!), but you can see and feel the effects in other areas. Maybe you have a raised spa wall with a spillway; do you see the ugly white residue on it? Perhaps you’ve noticed that the waterline tile doesn’t look quite so clean any longer. How does your hair feel when you get out of the pool… maybe like straw? Or do you feel like you have to run for the skin lotion after swimming because you feel dry and itchy? Hmmm, maybe you have noticed this without even realizing it!
