Sometimes a deadline really helps. I just know that what when I think something will take 4 hours it usually ends up taking more like 8-12 due to some crazy snag. So now, I just assume things will take forever, and I just get what I can done... Like today. I'm going out to see if I've finally got the autowater changer to stop leaking so I can finish setting it up. Instead, I go out to find someone has been munching on the slime coat of my beloved eels. So, that means a water change in the 385 gallon pond, a water change in the 180, transferring biomaterial to the pond including gravel and wood, and moving of bunch of fish.... all in 95 degree weather. An hour and a half later, I still haven't even looked at the auto water changer, and I've got to put together a treatment plan for my eels that won't wipe out the bio filtration but be kind to their sensitive skin. I'm thinking melafix and pimafix combined with oral antibiotics. So, yeah. Every project seems to take a thousand times longer than it should from things getting in the way.
I hope your pond comes along without too many crazy snags!
