Chemical Dosage Calculator

See how much Bayrol Hardness Plus (Raises Calcium Hardness) to use in our Chemical Dosage Calculator

Calcium hardness is the measurement of dissolved calcium in the water. For swimming pools, calcium hardness should be maintained at a minimum of 200 mg/l (ppm). Low levels can harm the pool and its equipment. Test the calcium hardness level of the pool water and if it is below 200 mg/l (ppm) use Bayrol Hardness Plus to increase the level.

Application Instructions for Hardness Plus

  1. Pre-dissolve the granules in a clean plastic container to a maximum quantity of 100g of granules to 10L of fresh cold water.
  2. Stir well until granules are fully dissolved.
  3. Apply solution near the inlets and with the circulation pump running.
  4. Repeat application to achieve the total dose required-(See Table Below)
  5. It is reccomended that the total dosing quantity is split into three equal applications with a minimum of 8 hours between each.
  6. Following dosing the pool water may appear cloudy, leave the circulation pump running until the water has cleared.
  7. Test water and adjust pH if necessary to an ideal range between 7.0-7.4.
