    • Twist black top section of EZ-Bio counter clockwise to unthread.
    • Pull the filter core off of the bottom section and away from the hard plastic core.
  3. Spray wash filter core with a strong garden hose or blast of water.** Spray wash the hard plastic core.

    • Push the filter core back onto the hard plastic core.
    • Twist the black top section clockwise onto the EZ-Bio plastc core.
