Quick Answer

Replacing IF internal filter foams is straightforward: turn off the filter, remove the old foam, rinse the filter body, and insert the correct new foam piece that matches your model.

Why Use Official IF Foams?

Foam is the cheapest component in a filter and always the first to give up. Cutting your own from a sheet never quite fits and tends to let water past the edges, so official pieces are worth the small difference in price.

IF Internal Filter Foams are designed to fit the IF range of internal filters, covering everything from the 200 l/h model right up to the 1200 l/h model. The amount supplied varies by model, so check your filter's flow rate before ordering.

Step-by-Step Replacement Guide

  1. 1. Turn Off and Unplug the Filter: Always switch off and unplug the filter before handling. Remove it from the aquarium to avoid spills and electrical hazards. Never work on a plugged-in filter—water and electricity don't mix.
  2. 2. Remove and Discard the Old Foam: Open the filter casing and take out the old foam. If it's stuck, gently squeeze it under running water to loosen debris. Discard it—reusing compressed foam reduces filtration efficiency. If the foam crumbles or smells foul, replace it immediately.
  3. 3. Rinse the Filter Body and Media Basket: Use dechlorinated water or old aquarium water to rinse the inside of the filter. Avoid tap water if possible, as chlorine can harm beneficial bacteria. Don't scrub the biological media—just a gentle rinse to remove loose debris.
  4. 4. Insert the New IF Foam: Take the correct new foam piece for your model (check the flow rate: 200, 400, 600, 800, or 1200 l/h). Slide it into place so it sits flat and seals against the edges. A poorly fitted foam lets water bypass the media—ensure it sits snugly.
  5. 5. Reassemble and Restart the Filter: Close the casing, reattach the filter to the aquarium, plug it in, and switch on. Check for leaks and ensure water flows through the foam evenly. If the filter rattles or flow is weak, check that the foam isn't blocking the impeller.
