thanks for all the help. I worked the pool over good this weekend. first I lowered the ph to 7.2. My alkalinity also came down to 130. i ran the filter all weekend with the salt cell at 100%. I also took 2 large red solo cups of Trichlor and sprinkled the powder around all the walls. I scrubbed like crazy. saturday morning i checked the Chlorine levels and used the dilution method. My reading was 30. The pool water looked really good. The Algea stain looked like it was fading. No visible Algea. Now my big question is, the algea stain, is it mustard algea imbedded in the plaster somehow? i looks like stripes on a zebra. . so I just took another water sample and here are the readings I got

PH 7.2
Alk 130
Free Chl 20
CYA 50
Hardness 380
Borax 45 PPM
