PLANTS WITH DISCUS

Steve Colley

NEDA Fall 2009 Meeting

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

Plants love Discus waste

Excess NH4 triggers algae

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
