water rotation

alright, i think my pump is dying. i notice not alot of water is falling into the built in filter send and return for my tank (it's pre-drilled) .... what could that mean?

You could have a kinked or clogged line... most likely, though, you have a dirty impeller. You can unscrew your pump and clean it out with a toothbrush and regular water. If you have a screen on your pump intake, make sure you clean it real good also. It is unlikely that your pump is dying. They either work or they don't.
