SO close to done!

So far this weekend, I've gotten the rain-barrel connector pipe glued in, the standpipe glued in, the growbed full of 400 pounds of clay pellets, the overflow pipe drilled and installed, the fish tank drained about 3/4 of the way and jacked up so I could put 2x4s under the back corners to level it, refilled it, tested the overflow, and done most of the pipe work for the sump pump back to the fishtank (it might work the way it is, but it's not as neat a job as I'd like - I'll fix that today).  I would have gotten the drain pipe done but I'd bought the wrong adapter and the stores were closed for the day.  I'll buy the right one today and *hopefully* get the very last of the system completed!
