Thank you,

It seems the water is very slowly starting to clear. I have vacuumed it several times to make sure there is nothing on the bottom. I added another dose of CYA to try and bring the level to about 50ppm this time I added it to the filter since the sock method didn't seam to work for me. I haven't been having to backwash the filter hardly at all, I wonder if it is really doing anything. I will continue with the high shock levels as suggested. At this point I am wondering if we will get to use the pool at all this year, which would be a shame if we didn't due to all the cost we have put in in the form of equipment and chemicals.

I'll adjust again tonight and check in the morning to see how much I'm losing overnight.

My numbers this morning are;
FC 8.5 added about 243oz bleach to get back to 15
PH 7.4
CC .5
TA 150
CH 70
CYA didn't check, out of test agent
