Parameters to Test: Ammonia, nitrite, nitrate, and pH
Reason: Regular weekly testing helps maintain stable water conditions. Early detection of any issues can prevent long-term problems and ensure a healthy environment for all aquarium inhabitants.
After Water Changes
Frequency: Test the day after a significant water change (20-30%)
Reason: Ensuring stability after water changes helps confirm that the new water conditions are within the desired parameters and that the change has not adversely affected the aquarium's ecosystem.
If Fish Show Signs of Stress or Illness
Frequency: Immediately test water parameters
Reason: Water quality issues often manifest as stress or illness in fish. Prompt testing and corrective actions can mitigate any adverse effects on the fish's health.
