Directions for use:

(Based on a 50 000l pool)

Use only as directed.

To increase Total Alkalinity (TA)

NB: 1kg of HTH® Alkalinity Up should raise the TA by approximately 10ppm.

1. To prevent possible staining from metals that may be present in your water, add 1 bottle of HTH® Metal Remover – follow label directions.
2. With the pump off, add 1kg of HTH® Alkalinity Up to one spot of the deep end of the pool.
3. Leave the pump off for 15 minutes.
4. Switch the pump on and continue with normal filtration.
5. After 12 hours, check the TA level.
6. If necessary, repeat the process of adding HTH® Alkalinity Up until the ideal range is reached.

NB: in the case of vinyl or colored pool linings, pre-dilute before adding to the pool.
