I've had this pond for about a year and just realized that this is also the pond forum. I just got a new 450 GPH pump at wal-mart for $30 and it is great. I'm going to add a waterfall and some plants very soon. My pond is only 30 gallons, which is probably the tiniest pond you can get. My parents wouldn't let me get a big pond because it was too expensive and the earth here in Virgina is literally rock solid. Currently I have 2 tadpoles and 1 salamander.
