10 Customer Questions
do you put the cotton side in front or back (there is a plastic back).. i didn't know if it mattered? thank you
Answer by • Nov 03, 2017
The cotton should be on the front side of the filter, that way it catches any bacteria that may be in the tank.
Is this filter slightly smaller at the bottom? 2.16 at top and 1.78 at bottom and 3.68 tall.
Answer by • Oct 06, 2018
The overall dimensions are 3.8 inches tall x 2.1 inches across at its longest point. The images do shows that the cartridge narrows a bit towards the bottom.
Do I need to turn off my filter system to just change the filter?
Answer by • Apr 23, 2018
We'd recommend unplugging the filter when changing the filter cartridge.
Will these filters work for 3.5 gallon tanks ?
Answer by • Nov 27, 2020
These Whisper Bio-Bags Small Filter Cartridge are designed to fit Tetra's Whisper PF10 (5-10 gallons) and 3i (up to 3 gallons) Power Filters.
