Foam and pebbles in a green plastic filter thing for my fish tank..?

What is it? I can't seem to figure out what it's for or how I use it. It's got a spongy foam thing at the bottom and little rocks at the top. It's got green plastic around it with slits in it so the water can get it. But I don't know what it is. If anyone knows, please help! :)



rj it's the filter connect the plastic pipe to it and watch the magic bubble appear (you got it in you r question filter)




It sounds like it is your biological filter, the place where the good bacteria can grow. The good bacteria will help filter out harmful toxins in your tank, and the sponge/rocks provide a lot of surface area for the bacteria to grow. The sponge part may be mechanical filtration (meaning it removes particles from the water) and the rocks are where the bacteria grow. That's my best guess from the description. Hope I helped.





There may be a place at the top where you can attach and air tube to it and at the other end of the tube an air pump. This will create water movement through the filter.
