pH cannot be maintained without alkalinity: always correct TAC first
It is the basic rule of water treatment and the one most often forgotten: a pH increaser does not work if alkalinity is low. In large facilities, skipping this step means wasted bags of pH corrector, uncomfortable swimmers, and water that never fully stabilizes.
- The pH plummets after each adjustment.
- Spending on correctors skyrockets.
- Chlorine and flocculant lose effectiveness.
- The pH remains stable.
- Corrections are minimal.
- All treatments perform at their best.
The method
Step 1, alkalinity. Step 2, pH
Also in pack format, the order is the same: first correct the Total Alkalinity and, once stable, adjust the pH. Both products are available in a 2 x 10 kg pack:
Alkalinity increaser pack
Bring TAC to 100-150 ppm in large-volume pools.
