Nobody who can come and pour a jug of bleach in during the first 5 days?

I would probably shock up to about 15ppm. If you are going to use trichlor, I'd suggest raising your pH up to around 7.7 or 7.8 with some 20 Mule Team Borax. Trichlor is very acidic and will drive your pH down. So, better to give the pH some 'wiggle' room.

What are you going to do about your pump? If you have a tree that drops a lot of debris in the pool, I'd be afraid to leave the pump running for fear of the basket stopping up and causing the pump to burn up.
