Tadpole tank set up . . .

We set up a 10 gallon fish tank. First we put the blue rocks in the tank.  I (Austin) put the water in by using a 128 oz., or 1 gallon, jug.  We also put a tiny shipwreck in it.  We put an aerator in it.  Also we put a filter in it that hangs on the side by a wire hanger that our Dad made.  The first time he failed and it didn't work.  I (Austin) added a giant rubber band and it worked.  We calculated the flow rate of the pump and it was 25 gallons per hour.  We also figured out that there are 6.64 gallons of water in the tank.
