Nitrogen Cycle
Solved!• Or is it?
Discus just too big
Natural Nutrients
Fish waste &
Food
Ammonia to Nitrite
Nitrite to Nitrate
Nitrate as Plant food
Plant Waste (O2) for
Fish

Paths to Planted Discus Tank Success
• Research THEN act*• Proper sequence*:
• Plants
• Inverts
• Ferts
• CUC
• 1st Fish
• Reduce inverts
• Repeat
• Gradual changes
• Change 1 thing at time
• Best to learn w/o Discus*
• Can‟t wait? Go low tech*
• Books
• On-line resources
