The pond is driving me insane. I thought I found the leak. When we set up the stream, we used two overlapping pieces of pond liner (a big no-no). I knew this wasn’t a good idea, but it worked for a couple of years, so I figured it was ok. While trying to find the leak, I did find a potential leak in this area, so I shorted the stream by a foot or so and removed the extra liner. I thought this did the trick, but it did not. So, I’m still looking. I’ve had to turn off the pump for the most part, because the pond is too low on water and I don’t want any more leaking out. I ordered an airstone and mini-pump that I’m going to start running as soon as it gets here. I’m not going to mess around with this any more until the water level comes back up.
