Green, cloudy and foamy is no way to go through life, son

I have added about 8 lbs of CYA a pound at a time using the sock method for a 20,000 gal pool. I have seen (or thought I saw) an increase to a level of "30-50" using a color strip but then a reading of 0 several days later. Perhaps I am mis-reading the strip. I have used 2 lbs of dichlor shock powder only once when we went away for a weekend, otherwise it has all been bleach.

Test strips are useless and unreliable. Around here, we refer to them as goofy strips. As we recommended to you back in an earlier post on 6/12, you need to get a good kit.

8 lbs. of CYA in 20,000 gallons would have added 50ppm. Do NOT add any more. Also do not use any more dichlor shock or trichlor tabs as they also contain CYA in them.
