Pool Chemical Calculator FAQ
Ideal levels, dosing questions, and how the free Australian pool calculator works.
How do I use the pool chemistry calculator?
Enter your pool type (Traditional Chlorinated, Saltwater, or Freshwater/Naked), pool volume, and your test strip results for pH, chlorine, alkalinity, and other parameters. Click calculate to get instant, tailored treatment advice for your Australian pool.
What pool types does this calculator support?
Our calculator supports three pool types: Traditional Chlorinated pools, Saltwater pools, and Freshwater/Naked pools (using ionizer systems). Each pool type has specific chemistry requirements that our calculator accounts for.
What test parameters do I need to enter?
Required parameters include pH, Free Chlorine, Total Alkalinity (TA), and Calcium Hardness (CH). For saltwater pools, you'll also need Salt Level. For Freshwater/Naked pools, you'll need Copper Level. Cyanuric Acid (CYA) is important for Traditional Chlorinated pools.
Is this calculator free to use?
Yes, PoolCalculator.com.au is completely free to use. No registration or email required. Simply enter your test results and get instant advice.
How accurate is the pool chemistry calculator?
Our calculator uses industry-standard chemistry rules and ideal ranges for Australian pools. However, always follow manufacturer instructions for your specific pool equipment and consult a pool professional for complex issues.
Can I share my pool test results?
Yes! After calculating your results, you can share them via a shareable URL. This makes it easy to get advice from pool professionals or share with family members.
What are ideal pool chemistry levels for Australian pools?
Ideal chemical levels vary depending on your pool type. Here are the recommended ranges for each:
Traditional Chlorinated Pools
| Parameter | Ideal Range |
|---|---|
| pH | 7.2 - 7.6 |
| Free Chlorine | 1 - 3 ppm |
| Total Alkalinity (TA) | 80 - 120 ppm |
| Calcium Hardness (CH) | 200 - 400 ppm |
| Cyanuric Acid (CYA) | 30 - 50 ppm |
Saltwater Pools
| Parameter | Ideal Range |
|---|---|
| pH | 7.2 - 7.6 |
| Free Chlorine | 1 - 3 ppm |
| Total Alkalinity (TA) | 80 - 120 ppm |
| Calcium Hardness (CH) | 200 - 400 ppm |
| Cyanuric Acid (CYA) | 60 - 80 ppm |
| Salt Level | 2,700 - 4,500 ppm |
Freshwater / Naked Pools (Ionizer Systems)
| Parameter | Ideal Range |
|---|---|
| pH | 7.2 - 7.6 |
| Free Chlorine | 0 - 0.5 ppm |
| Total Alkalinity (TA) | 80 - 120 ppm |
| Calcium Hardness (CH) | 200 - 400 ppm |
| Copper Level | 0.2 - 0.4 ppm |

How much liquid chlorine should I add to my pool?
For common 12.5% liquid chlorine, about 400 ml raises free chlorine by roughly 1 ppm in a 50,000 L pool. Use the liquid chlorine calculator chart for liquid dosing. The main calculator estimates granular chlorine doses for Amazon Australia products.
How much pool acid do I need to lower pH?
For a 50,000 L pool, about 50 ml of muriatic acid lowers pH by roughly 0.1. Never add more than 500 ml at a time. See the pool acid calculator guide.
How much pool salt should I add to a saltwater pool?
As a guide, about 50 kg of pool salt raises salinity by roughly 1000 ppm in a 50,000 L pool (kg ≈ litres × ppm increase ÷ 1,000,000). Most Australian salt chlorinators target about 2700–4500 ppm. Use the pool salt calculator or the main pool chemical calculator for an exact dose.
Is there a free pool chemistry calculator for Australia?
Yes. PoolCalculator.com.au is free, with no sign-up. Enter test strip results for traditional, saltwater, or freshwater pools and get dosing advice instantly.
