Usage & Maintenance Guide

To maximize the biological efficiency of your new ceramic rings, follow these simple setup steps:

• Preparation: Always rinse the ceramic rings thoroughly in dechlorinated tap water before adding them to your filter to remove any residual dust from manufacturing and transit.

• Placement: Position this biological media after your mechanical filtration (like sponges or filter pads). This prevents solid waste from clogging the microscopic pores where your bacteria live.

• Safe Maintenance: Never wash biological media under raw tap water, as the chlorine will instantly destroy your beneficial bacteria colony. When necessary, gently swish the rings in a bucket of old aquarium water during a routine water change.
