I'll have to look around for a bulk bleach supplier. I'm using a gallon (8.25%) every 2 to 3 days in the summer just to maintain 3-5ppm. (CYA is at 50) Shocking the pool with bleach is going to really be a pain.
Before we re-plastered, I used the fine granual dry shock. That worked OK, but I'm trying to get away from that.

I discovered re-purposing my oil filter pliers a couple of weeks ago when I couldn't find my strap wrench and needed to tighten the quick disconnect on my filter pump inlet. They really do work great!
