Yeah sorry, 8 is when pump is off. So 24 is my normal psi. I'm thinking 24-8=16. 16 is the "true" number?
Mostly cloudy, chance of Floc?

Replace that gauge, once they don't read 0, they are not reliable anymore. New gauges are cheap and easy to get (hardware stores, pool stores, etc.).
If 16 was accurate you would want to backwash at 20 psi.

80*
FC 8.0
CC 0
pH 8.0
TA 90
CYA 70
Added sodium bisulfate for pH.
About 90% better. Still a little hazy. Adding DE once a day, after two hrs pressure goes up so I backwash and a lot of dirty water comes out. Backwash w/o DE, not so much. I noticed pH went up and TA was cut in half since last weeks reading. Any reason why?

TA goes down a little each time ph is lowered. Also if you have low TA fill water and you are having to add makeup water due to splash out or leaks...that will lower it too.
From 180 to 90? I just lowered pH today AFTER the latest readings. The past three weeks no one has been in the pool because of this problem. The backfill water added was about 2". Will it get lowered that much? Thanx
No, not that much even if you fill water was really low in TA. Are you certain you are doing the test the same? Review the extended test kit directions, you may have had a static electric charge issue with your dropper tip when you did the first test: http://www.troublefreepool.com/extended-test-kit-directions-t25081.html#p206395
