My k2005 says cya approx 100. the test strips say approx 40-50. I've tested each twice with same result. My cya was about 80 last season before close. Upon closing I drained about a 1/3. I cannot see how it could be 100 per the k2005. I have not added any CYA. I did add the bleach as instructed last night. The smell of the water seems to have dissipated, but clarity and overall quality is still suffering. I did do the diluted test via k2005 a couple times before adding bleach.

1st go chlorine off the scale
2nd go with half/half dilution looked to be off scale but close
3rd go with .25 and .75 dilution looked to be about 2ppm

after bleach this morn
1st go chlorine off the scale
2nd go with half/half dilution looked to be off scale but close
3rd go with .25 and .75 dilution looked to be about 4-5ppm

Am ordering the k1515 but this is the best I have for now.
Again thanks.
