Quick Answer

Replace all three EF-Booster filter foams at once to keep your external filter working efficiently and your aquarium water clean.

Why Replace All Three Foams Together?

The EF-Booster filter uses three foam layers, each with a different color and density. Over time, all of them trap debris and lose their effectiveness. Replacing only one layer while leaving the others clogged can reduce water flow and filtration quality. Using the full set ensures the entire canister is refreshed at once, giving your filter a clean start.

What to Check Before You Start

Before you begin, make sure you have the new foams on hand and that they match the dimensions of your filter (10.6 x 3.2 cm). Also, turn off and unplug the filter to avoid any accidents. Have a bucket or towel ready to catch any water that spills from the canister.

Step-by-Step Replacement Guide

  1. Unplug and Disassemble: Turn off and unplug the external filter. Open the canister lid and remove the media basket or tray that holds the foams. Always unplug before opening to avoid electrical hazards.
  2. Remove Old Foams: Take out the old blue, black, and yellow foams. Discard them or rinse if you plan to reuse them (but replacing is recommended). Check the condition of the old foams—if they are compressed or falling apart, replace them.
  3. Rinse the Media Basket: Rinse the media basket or tray with dechlorinated water to remove any accumulated debris. Do not use soap, as it can harm fish. Use water from your aquarium to preserve beneficial bacteria.
  4. Install New Foams: Place the new foams in the correct order: usually blue first (fine), black (medium), and yellow (coarse). Refer to your filter manual if needed. Ensure the foams sit snugly without gaps to prevent water bypass.
  5. Reassemble and Restart: Put the media basket back, close the canister lid, and reconnect the hoses. Plug the filter back in and check for leaks. Prime the filter before starting to avoid air locks.
