I know this has been a long thread.. but I did want to post an end result update.. So maybe others will be able to see how BBB, patience, trying the ideas found here... and working at it ..will eventually pay off.

todays readings:
FC 6
CC 0
pH 7.4
Alk 90
CYA little over 20.

Because of the cloudy water before.. I believe (in previous posts) I was getting an untrue CYA reading. I might try and bring that up closer to the 40-50 range. I am burning up too much bleach too fast.. on sunny days. I usually add a 96 ounce jug of 6%.. every other evening.. but this year its been every evening. ( 24 X 4.5 AG round = 13500 to 14000 gallons ).

What is your experience with adding bleach? every day? twice week? etc?

Finally.. thanks to everyone.. your suggestions and comments are appreciated..

Here's a couple of pics taken this morning.. just to show clarity. Compare them with pics at the beginning of the thread.
