Further Cleaning: The gravels inside absorb excess damaging substances and release trace elements. And the ceramic rings can cultivate beneficial substances. Always keep water fresh.
For 50 Gal Tanks: Measure 3.1" R x 6" H. Fit for 20-50 gallon fish tanks. You can change the sponge sequence at will and customize the filter materials according to the breeding density of the fish.
Quiet Aeration: Air powered and cause no disturbance to your daily life. The wide duck-billed air outlet port brings more bubbles to promote oxygen circulation.
Easy to Clean: The filter can be easily detached for cleaning. Rinse the sponges every 2 to 4 weeks with aquarium water ONLY. Avoid soaking or washing them in tap water! Replace the white sponge every 2-3 months!
