Hey guys...im looking to swap out my filter. I currently have the Whisper 2-10 internal filter which the current is to high for him. Ive tried putting pillow stuffing(cant find filter floss) and that is just not working out. Its causing the back of the filter to back up and cause water floods out the back of the tank onto the wire. So im torn between getting the whisper 3i(which is for up to 3 gallons), the red sea nano, or the toms aquarium internal filter. recommendations? likes/dislikes?
