Slime behind Niche Light

[selectstar]

18.5 x 38.5 Grecian 3ft shallow, 8.5ft deep. My assumption has always been 20-22k.
I did manage to get the water tested by a local store. This guy seems to be a straight shooter and I have no reason to distrust him.

After the bleach, I brought a sample to him this morning. The results follow.
CYA = 96 (Close to what I read from K2005)
ph = 8.1 (This blew me away considering it was below 7 before bleach additions)
fc = 10 (Said this is as high as he can test)
tc = 10
ta = 109
adj ta = 80
appearance = mod to severe cloudy (my assessment)
temp = 78
salt = not tested as I have not added any as of yet

Will retest ph this evening and post.
Hope this helps. Thx

Your volume estimate seems reasonable. Your pH and alkalinity levels are fine for now.

So . . . go ahead and add 2 gallons of chlorine each evening. Test using the DPD tabs @ 1:4 dilution (multiply x5) every other day. Skip dosing at 20 ppm FC; resume @ 15 ppm.

Brush the pool completely.

Report FC & CC results once you get the K-1515
