Another exciting thing that worked out: I let the hose continue running till it overflowed. As planned (hoped) - it flowed over and out the back end, toward the woods. We thought that would happen. Hoped that would happen. But I was sort of holding my breath till it actually did.
It is now 7:00 am Saturday morning. I hope to be outside by 8, since today is supposed to be a scorcher. We might work on the electrical this weekend but hubby is doing a big window restoration project. For sure, I will be working on prettying up the edges and planting!
It's going to be super cool to turn on the pump. I am hesitant to do it, though, since I know they are made to run continuously. I don't know if a bunch of off and on will be good for it. It will be neat to get it running and adjust the flow between the bog, the circulation jet, and the "breather pipe" at the top of the bog. Hopefully there will be enough oomph to have all three working together.
