The Nitrogen Cycle
The most critical concept in fish keeping. Fish waste produces Ammonia (Toxic) → Bacteria turn it to Nitrite (Toxic) → Bacteria turn it to Nitrate (Safe in low levels).
Ammonia (NH3)
Critical
Caused by waste, uneaten food, dead plants.
Safe Level: 0 ppm
Action: Water change immediately. Use detoxifier (Prime).
Action: Water change immediately. Use detoxifier (Prime).
Nitrite (NO2)
Critical
Product of ammonia breakdown. Suffocates fish.
Safe Level: 0 ppm
Action: Water change. Add aquarium salt (if species allows).
Action: Water change. Add aquarium salt (if species allows).
Nitrate (NO3)
Monitor
End product. Removed by plants or water changes.
Safe Level: < 40 ppm
Action: Routine water changes if high.
Action: Routine water changes if high.
pH Level
Variable
Acidity or alkalinity of the water.
Range: 6.5-7.5 (Community), 8.0+ (Cichlids)
Note: Stability is more important than a "perfect" number.
