- Test carbonate hardness (KH) to check alkalinity.
- Keep hardness levels stable to avoid stress on aquatic life.
- Adjust hardness with additives if needed.
Detecting Contaminants
Contaminants can harm your hobby system. Test for chlorine, ammonia, nitrites, and nitrates. These come from tap water or waste buildup.
| Contaminant | Why Test? | Safe Level |
| Chlorine | Harms fish and plants | 0 ppm |
| Ammonia | Toxic to aquatic life | 0 ppm |
| Nitrites | Stressful and toxic | 0 ppm |
| Nitrates | High levels hurt fish | Below 40 ppm |
Common Water Treatment Methods
Water treatment is important for hobbyists who want clean and safe water. Different methods help remove dirt, germs, and chemicals.
This guide covers three common ways to treat water: filtration, chemical treatments, and UV sterilization.
Filtration Options
