Wifezilla, hopefully you can help me out with some questions I have about your system....sorry if they might be dumb!!
So, just to make sure I'm not making any mistakes: You have the pump sitting in the bottom of the pond, in a cage. The outflow of the pump goes through a hose to the bottom of the flower pot. And then, what? Just the pressure from the pump will push the water through the filter, up to the overflow hole?
Now that the system has been running a few months, is your water staying clear? How many ducks are using your pond? How often do you have to dredge all that sediment out of the bottom?
Thanks for letting me pick your brain!
