Heh...heh..heh, 50K gal pool laughs at 4 pounds of CYA.
I know I hate adding the stuff but it is a necessary evil.

Back from my trip and well rested. Vacuumed entire pool and looking good. Still need to adjust the chems but going slow.

Today's tests
FC - 1.5
CC- 0 or maybe .5
TC - 2.0
PH - 7.2 will add 20 lb of BS to increase by .2
ALK - 90 would like to get this up 20 - 30 PPM, maybe after PH adj.
CAL - 110 vinyl pool just felt lik erunning test
CYA - still less than 20ppm but a little cloudier than before.
