ok so here are the readings and my method
20K gallon IG with pool cover
CL 0
PH - 7.3
CALC - 290
ALK - 70
CYA - 20
I usually start the year by doing 1.5 gallons of muriatic and after 3 hrs start hammering with 4 gallons of liquid bleach ....my problem is the bleach usually gets eaten immediately because CYA is low ....usually I have 0 CYA at beginning of year so is it ok to add bleach with 20 CYA or wait .....thanks!
