My family will be going on vacation from a Friday (7am) until the following Saturday (4pm) , essentially almost 9 days. My neighbor, who usually looks after my house / pool, is going with us. I may have an option for someone to add bleach at some point during week, maybe. Here are my questions / numbers:
1) Current CYA is 65, I have been keeping FC at 7ppm, letting it drift down to 5ppm and adding bleach around 7pm to get it back up. Consumption has been around 15 - 30 ounces daily depending on weather and swimming activity, sometimes 45 oz.
2) Suggestions on how to keep this pool sanitized enough to last this vacation WITHOUT adding any bleach. My thought was, at the very least, to get this pool to shock level just before we leave, and leaving the solar cover on the entire time (both obvious). I do have some 3" pucks to use if I need them, but I wonder how much CYA they'll add if I float two during that week. With CYA at 65 already would like not to get too much higher, but I was at 70 at start of season (added water, kids splashing, initial backwashing, etc.). How many pucks should I float? or should I "skimmer" them?
3) Should I just find a life form that can simply add a Full (128oz.) gallon of bleach the middle of the week without mucking up my liner/ solar cover / themselves?
Thanks in advance for any and all suggestions ...
