Poor Water Quality or Toxins

Poor Water Quality or Toxins — Start Here

If your fish seem stressed, sluggish, or unwell, poor water quality may be the cause — even if the water looks clear.

This page will help you address harmful toxins and restore a safe, balanced environment for your pond fish or koi.

Common Causes of Poor Water Quality

Poor water conditions are often caused by:
• Fish waste buildup
• Uneaten food and debris
• Chlorine or chloramine from water changes
• Imbalanced biological filtration
• Sudden environmental changes

These issues can stress fish quickly if not corrected.
