If flow rate slows and or there appears to be debris, scale or mineral build-up on the outside of the filter elements, follow these instructions to clean them:

  1. Empty and disassemble the Phoenix Gravity New Millennium Edition™ Filter Elements from the upper chamber of the gravity filter system.
  2. Gently scrub the elements with a stiff brush or Scotch-Brite® pad under cold running water (never apply soap or other cleaning agents to your filter elements).
  3. Re-prime the elements and reinstall them in your gravity system.
  4. Lastly, fill your gravity system and perform a red food coloring test as described in the filters instructions to ensure your system has been assembled correctly, and that there are no internal leaks in your system.
