Using Bleach in the Pool

[Schooled by Pool]

Update: I have been keeping the Chlorine level high, 10+ FC with an occassional shock. It is still cloudy. But, I can see the bottom of the shallow end and it looks like I can see about 5 ft. down into the deep end. I have been brushing the walls, and I vacuumed over the weekend. Hoepfully, we are close to the end of this mess.

Last night I shocked the pool again. Before I shocked, the pool was 16.5 FC, .5 CC, 7.6 ph, 110 TA, 370 CH, 150 CYA. I added 4 gallons of liquid shock from a pool store (Unstabilized chlorine, 10% or 11% depending on which part of the label you read. Up until now, I have been using store bought chlorine (6% Dollar General)). I have gone through a lot of chlorine and want to try a higher concentrate with less bottles.

After I shocked pool, I tested the FC 2 hrs later. It was 27.5.

This morning I tested. It was 27.5 FC, 0 CC, 7.8 ph. 120 TA, CH 370. So the ph went up, which was odd. But, the other odd thing was when I tested the TA, it turned from green to a pale yellow color, rather than a pinkish red color. I tested it twice, same results. Why did the color change? Also, why did the ph go up?

I am assuming all the algae in my pool is dead and I am waiting for everything to settle, due to the FC and CC. Is there anything else I need to do before I get someone to shut down the pool for the winter?

Thanks for your help.
