Cleaning Instructions: Have a bag or container ready to put the sponge in once removed from the filter. Lift the water and sponge out to catch the majority of debris that will come off while removing. Next, use the aquarium water and squeeze out the debris from the sponge. Discard the water and get more water from the aquarium and repeat until sponge filter is mostly free of debris.
Reinstall the sponge and wait for a couple hours for the water to clear back up from the debris released when removing and reinstalling.
Filter Fitment: All filters (cut to size for best fit)
