To increase Total Alkalinity (TA)
NB: 1kg of HTH® Alkalinity Up should raise the TA by approximately 10ppm.

- With the pump off, add 1kg of HTH® Alkalinity Up to one spot of the deep end of the pool.
- Leave the pump off for 15 minutes.
- Switch the pump on and continue with normal filtration.
- After 12 hours, check the TA level.
- 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.
