Entry 25 - Busted Aquarium Filter

I was doing my weekly aquarium cleaning today.  I change the water at least once a week, and I clean the aquarium filter at least once every two weeks.  Today, I changed the water and was suppose to clean the aquarium filter also when I noticed that the pump was no longer running.  My aquarium needs the pump since not only does it help in cleaning the water, but it also circulates it, providing oxygen to the water.  Without the pump, the aquarium will run out of oxygen for my fishes.  I tried looking for my extra pump but couldn't find it.  The only one I found was the aquarium filter for a small 10 gallon aquarium.  My aquarium is a 50 gallon tank, so that 10 gallon filter won't be enough.  I just hope it helps for at least a couple of days, until I get to repair my old pump or be able ot buy a new one.
