Ya. Kithy, most people aren't going to add fish to their ponds right now. These are the coldest months of the year and adding fish that aren't acclimated to the cold will kill them. You will have to hold out until spring. Adding another filter does sound like a temporary solution, tho. If you can get something like an AquaClear that would be even better.
Olympia! Did the vast amount of poop break your gravel vac?!
