Correct Pool Settings Guide for Onga/Pentair Salt Chlorinators
To ensure your pool stays clean, safe, and comfortable, maintaining the correct chemical balance is essential. Here’s a guide for ideal water parameters and adjustments to help you achieve perfect balance, with a focus on Onga/Pentair salt chlorinator systems.
| Parameter | Australian Standard | Ideal Reading/Range | How to Increase | How to Decrease | Testing Frequency (Peak Season) |
|---|---|---|---|---|---|
| Free Chlorine (ppm) | 1 – 3 | 1.5 – 3 | Increase output of chlorinator. Add chlorine. Increase filtration time | N/A | Weekly |
| pH | 7.2 – 7.8 | Concrete & Tiled Pools: 7.4-7.6 Other Surfaces 7.2-7.4 |
Add buffer or soda ash (Sodium Carbonate) | Add Muriatic Acid | Weekly |
| Total Alkalinity (ppm) | 80 – 300 | 80 – 150 | Add Sodium Bicarbonate | Add Muriatic or Dry Acid | Weekly |
| Calcium Hardness (ppm) | 90 – 300 | Concrete & Tiled Pools: 200-275 Other Surfaces 100-225 |
Add Calcium Chloride | Partially drain & refill pool | Weekly |
| Cyanuric Acid (ppm) | 30 – 50 | 30 – 50 | Add Cyanuric Acid | Partially drain & refill pool | Regularly |
| Salt Level (ppm) | 4000 – 7000 | 4500 - 6000 (Above ground pool models on |
Add salt | Partially drain & refill pool | Regularly |
Guidelines for Adjustments
- Free Chlorine: To raise chlorine levels, add chlorine directly or adjust your equipment’s output.
- pH: Increase pH by adding buffer or soda ash; reduce pH with muriatic acid for proper balance.
- Total Alkalinity: Use sodium bicarbonate to raise alkalinity or muriatic/dry acid to lower it.
- Calcium Hardness: Adjust by adding calcium chloride, or reduce by partially draining and refilling the pool if levels are too high.
- Cyanuric Acid: Increase with cyanuric acid and decrease by partially draining and refilling.
- Salt Level: Check monthly. Add salt as needed, or drain and refill if levels are high.
Regular monitoring and adjustment following this table will keep your pool within optimal parameters, enhancing the effectiveness of your Onga/Pentair salt chlorinator for a clean, comfortable swimming environment.
Maintenance Guide
For regions with high calcium hardness, periodic cleaning of the electrode is recommended to ensure optimal performance. Use a Salt Chlorinator Cell Cleaner or a 1:10 solution of hydrochloric acid to water, and always follow local disposal guidelines for the cleaning solution to protect the environment.
