Melpool Cal is used to prevent and remove limescale and metal ions (or rust stains) in your pool.
For the best results, the product must be evenly distributed over the water surface, approx. 30 cm away from the edges.
Make sure the filter installation is operating, only then will the limescale stabiliser be distributed properly.
For preventive treatment: the product dosage depends on the hardness of the water.
For water hardness from 350 to 500 ppm, add 100 ml Melpool Cal per 10 m³ water every 3 months.
For water hardness from 500 to 750 ppm, add 200 ml Melpool Cal per 10 m³ water every 2 months.
For water hardness greater than 750 ppm, add 200 ml Melpool Cal per 10 m³ water every month.
To remove lime scale:
To remove lime scale, add 200 ml Melpool Cal per 10 m³ water. Do so as close as possible to the lime scale and thoroughly brush the area.
Note: Always add this product to water, never the other way around. Keep sealed in a cool, dry place away from children.
