How often should I change the cartridge on a
Power Filter?
The cartridge should be changed once a month.
How often
should I change the water in my aquarium?
You should do a 25% water change every 2 weeks. There is no reason to remove
the fish during the water change. Make sure you stir the gravel or use a
gravel cleaner during the water change. When adding water back in to the
aquarium, use Tetra AquaSafeŽ to remove the chlorine and chloramine. Try not
to do over a 50% water change, this will remove the beneficial bacteria and
can cloud the tank.
Can the Power
Filter cartridge be rinsed off and reused?
No, it should not be reused. Change the cartridge every 4 weeks to ensure
the best filtration.
Does the
WhisperŽ Power Filter put oxygen into the tank?
The WhisperŽ Power Filter cleans the water and puts in oxygen. As the water
flows back in to the tank, it breaks the surface area and adds oxygen to the
water. It works like a waterfall. It can only benefit your tank to have
extra oxygen, but the WhisperŽ Power Filter is all you need.
