Even though we like to focus on creating a healthy ecosystem with our ponds to keep the water healthy (and not on testing and chemicals), it’s useful to know some recommended levels. Here are the ranges that Jungle Labs recommends:
| Harmful If Out of Range | low | ideal | high |
| pH | below 6.8 ppm | 7.2 – 7.6 (7.0 is neutral) | over 7.6 ppm |
| hardness | below 50 ppm | 50 – 150 ppm | over 150 ppm |
| alkalinity | below 100 ppm | 120 – 180 ppm | above 200 ppm |
| Harmful If Detected | safe | unsafe |
| ammonia | 0 – .25 ppm | over .25 ppm |
| nitrate | 0 – 200 ppm | over 200 ppm |
| nitrite | 0 ppm | over .5 ppm |
