Mechanical Filtration: The sponge can effectively trap debris, food residue, wastes or other impurities in water. Prevent them from entering the aquarium to keep water clean.
Deep Cleaning: Contain mini filter balls on the bottom. They are helpful for blocking large particles in the water and accumulating beneficial elements. Provide biological filtration to fully remove excess damaging substances.
For 20 L Tanks: Size: 5 x 6 cm (W x H). Fit for fish tanks up to 20 L. Suitable for the breeding and feeding of various ornamental fish, shrimp or fish fry.
Quiet Aeration: Air powered filter – required air pump: < 2 W; jetting volume of air stone: 0.6 L/min. Produce a cascade of dense bubbles in the water, greatly promoting oxygen circulation to keep your fish healthy.
Easy to Clean: The filter can be easily detached for cleaning. Rinse the sponge every 2 to 4 weeks with aquarium water ONLY. Avoid soaking or washing it in tap water! Replace the white sponge every 2-3 months!
