Trichlor Pool Shock Calculator
Calculate the amount of Trichlor shock needed. Remember: Trichlor adds Cyanuric Acid (CYA) and lowers pH.
Technical Comparison
| Factor | Trichlor | Cal-Hypo |
|---|---|---|
| PH Impact | Lowers | Raises |
| Calcium Impact | Zero | Adds Ca |
| CYA Impact | Adds CYA | Zero |
The CYA and pH Trade-off
For every 1 ppm of chlorine added by Trichlor, you also add ~0.6 ppm of stabilizer and lower pH.
