Test the water regularly to ensure a stable environment.
Maintenance Tips
Perform Weekly Water Changes
Replace 20–30% of the water every week to maintain excellent water quality.
Clean the Glass
Use an aquarium-safe magnetic cleaner to remove algae from the viewing panels.
Trim Live Plants
Prune overgrown plants to preserve the intended layout and improve water circulation.
Service the Filter
Clean filter media using removed aquarium water to protect beneficial bacteria.
Inspect Equipment
Check heaters, filters, and lighting regularly to ensure they are operating correctly.
Safety Considerations
A kitchen aquarium requires a little extra planning.
Keep the aquarium:
- Away from direct heat sources
- Away from grease and cooking fumes
- On a strong, level surface
- Close enough to electrical outlets without creating trip hazards
- Protected from accidental impacts in busy walkways
Ensure all electrical equipment uses drip loops to reduce the risk of water reaching power outlets.
Common Mistakes to Avoid

Heat and grease can affect both the aquarium and water quality.
Overcrowding
Too many fish create unnecessary waste and increase maintenance.
Overfeeding
Excess food can quickly pollute the water.
Ignoring Water Quality

Very small aquariums are less stable and often require more frequent maintenance.
