Calcium & Lime Build up in swimming pools

Dear John.

We have a rather large and difficult problem with lime in our water. Our imitation rocks by our pool and the slasto surround inside the pool have gone white with the lime. What do you reccomend on how we can remove this build up.


If the calcium hardness is too high, the result will be scale formation on all pool surfaces. The filter and pipes become clogged, reducing water flow and filtration efficiency. The water becomes cloudy and swimmers complain of eye irritations. Free treatment Instructions

Reducing calcium hardness is very difficult. Either replace some or all of the water in the pool, or add chemicals that will keep the calcium in solution and prevent it from depositing out. If the calcium hardness is high, we recommend that you consult a pool professional.

I would personally recommend using ozone see Ozone, swimming pool water treatment with no chemicals

Ozone helps remove metals which can discolor water and stain pool surfaces, prevents calcification, and softens the water. Ozone has no effect on pH or total alkalinity, so fewer chemicals are needed to adjust pH and water balance. Ozone destroys oils and converts them to carbon dioxide (CO2). The use of enzymes to remove oils is not necessary and bathtub ring formation at the waterline will be reduced.

When properly sized and installed, a corona discharge ozone generation system should result in easier to maintain, less costly, and better smelling, better tasting, and better quality pool water.
