When I got my tank it had a hang on filter. It started leaking so I got a new filter. My new filter is a Whisper filter. The old one had some sort of ceramic type "beads". They are around a half-inch in size and sit in the bottom of the filter tank. What are these and what are they for? Should I put them in the tank of my Whisper filter? Does a bubble wand actually add any oxygen to the tank or are they purely for show?
