Perform Weekly Water Changes

Service the Filter
Clean filter media in removed aquarium water to protect beneficial bacteria.
Inspect Equipment
Regularly check heaters, pumps, and lighting to ensure everything is functioning correctly.

Limited Maintenance Access
Allow enough space behind or above the aquarium for routine maintenance and equipment servicing.

Too many fish can reduce water quality and increase maintenance requirements.
