More Information


When performing routine maintenance, save a portion of removed aquarium water in a fish-safe container. Disassemble the sponge filter and separate the sponge from the hardware. Use the saved aquarium water to clean the sponge. Squeeze it, shake it, and rinse it out in the fish-safe container. When the sponge looks clean, reassemble the sponge filter and reinstall.
