Hi Will be gone for 4 days. There is someone home to put in chemicals if need be but he wont be testing the water. I leave tomorrow. I just tested and current numbers are FC 4.5, CC .5, PH 7.7, TA 160, CYA 55. I am going to add 3.7 oz of bleach and 3 oz dry acid tonight. I usually have to add about 20 oz of bleach every other day as well as small amt of either dry acid or borax. But while I'm gone, I was thinking of having him add only 16 oz of bleach every other day til I get home, to be conservative and hopefully keep everything stable enough til I get home. The weather here will be 60s during day and 40s at night while I'm gone. Thanks for any suggestions you might have for me.
