How to Reduce Nitrates in an Aquarium
A rising nitrate reading is a signal to review your routine.
A rising nitrate reading is a signal to review your routine. Start with the checks below, then choose only the products your tank needs.
What to do
Test and record
Measure nitrate before and after a water change. Check tap water too if levels keep returning.
Change water regularly
A partial water change removes dissolved nitrate immediately. Match temperature and condition tap water.
Remove waste
Siphon debris, avoid overfeeding and clean the mechanical filter without stripping the entire biofilter.
Review long-term control
Appropriate plants and biological media can help, but they work gradually and do not replace maintenance.

Purigen removes organics before they break down; it does not directly remove nitrate. Seachem de*nitrate needs the low flow specified on its label to target nitrate.
