Background: I recently bought a house with an in-ground pool I estimate at about 12,500 gallons. It was originally foreclosed, but fixed-and-flipped. At the time I purchased it the pool water looked to be in good shape but I knew it had to be resurfaced, so I didn't put any effort into it. Then life happened and the resurface got delayed. To make matters worse, a live oak started shedding its leaves and then pollen into the pool. Of course this produced algae...
I read on this site about what I needed to do before I started, so I loaded up on bleach and CYA. When I started on Sunday, the pool was a nasty dark green swamp with practically no translucence. I put the CYA in and began blasting it with bleach. I spent the whole day Sunday adding bleach, testing with 5-way strips every 30-60 minutes (I know, but I had to wait for the k-2006 kit to arrive), dredging with the leaf rake, scrubbing with the brush, and cleaning the filter. I forget the number, but I used about 12 gallons of bleach that day and the transformation between then and the next day was tremendous. It changed to a bright, slightly translucent green. The next day I tested and added bleach every hour or 2 and cleaned the filter 2 or 3 times. By Tuesday I saw some further improvement. It became more of a light pastel green.
Unfortunately, there's been only very minor visual improvement between Tuesday and today. It's still a pastel green, and I can see maybe 1.5 feet deep. Is this slowness normal? The numbers seem to be a bit better: FC is decreasing less, CC is a little lower. The only number that seems really out of whack to me is the Calcium is a little low, but I don't care about the plaster since I'm getting it resurfaced in a month anyway.
Also, I have lots of pockets of super-small bubbles on the surface of the pool. They're so small that at first I thought it was dead algae. Could this be caused by the low CH?

CYA 32 (ish - I have trouble being accurate with this test with the k-2006)
