Green Water - mustard algae

[SAP_Pete]

Hi Guys,
good to be here, and I read a lot already. Here's my current dilemma:

Water kept turning green, with greenish / yellowish algae clinging to the walls. The wife kept dumping trichlor powder, which didn't seem to do much, so I started reading up on stuff here. Got a CYA test strip (all they had at the pool store), and CYA was through the roof.

1. Emptied 90% of the pool water (loaner pump had to go back at this point)
2. Refilled with tap water
3. Tried to balance with bleach, but water turned green pretty quickly
4. It's pretty hot here (daytime 115 degrees this week), so that doesn't help

Got my Taylor K-2006 yesterday, and tested:

FC 17
CC 1
pH 7.8
TA 160
CH 140
CYA 70

Added 1/2 gal acid last night, and checked this morning:

FC 10
CC 0
pH 7.2
TA 140
CH 125 (used the 25 parts per drop this time)

The pool is still green. I can still see the floor at the deep end (6 feet). Water circulates through the pool cleaner - pump - filter - spa - overflows back into pool.

I've used some leftover trichlor powder and then regular bleach.
My question: Do I need to hit it harder / for a longer time with bleach ? Should the pool clear up if the algea is truly dead, or does green mean there is still algea alive ?
