The replacement grid fits perfectly in my Whisper 40i filter. It’s easy to install and the filtration has improved noticeably. My tank has been cleaner and more stable since switching to this foam grid.
Sally Avery –
Works well with my 20i filter. The foam holds up well after a few weeks of use. I noticed better water clarity and less algae growth. Installation was straightforward.

I replaced the old foam with this kit and it’s been running smoothly for over a month. The surface area helps with nitrifying bacteria growth, which keeps the water chemistry balanced.
