Whisper Aquarium Filter Upgrade

thingiverse

Whisper Aquarium Filter Upgrade, consists of three parts. 1. In tank pre filter designed to be used with cut size filter media 2. Insert allows you to put loose media and forces water through the loose media 3. what I call the Whisperer, a part attached to the front of filter to lessen the noise of the water dropping and reduces surface agitation ( likely not a good idea unless you have planted tank. I have a planted tank and don't want the co2 I injecting to get out.)
