Here are the 2 filters I have with 2 carbon filters in each one totaling 4 cartridges. Do I need to remove these while doing a fishless cycle?
Whisper® PF-60
Mechanical Filtration -- To remove particles such as uneaten food, bits of plants, fish waste, etc., from the water
Biological Filtration -- To provide for the growth of a colony of beneficial bacteria that will eliminate harmful toxins in the water
Chemical Filtration -- Activated carbon removes compounds that cause odors and discoloration of the water
Designed for ease of use, Whisper® Power Filters use Bio-Bag® filter cartridges for mechanical and chemical filtration. The disposable Bio-Bag®s remove waste particles, discoloration and odors from aquarium water. Bio-Bag®s are easy to change, making it easy to maintain clear aquarium water.
