I tried searching for this first but came up with so many results and didn't see one that matched my question, though I did not look through all 187 pages of results. I will be leaving for vacation soon and will be gone for 2 weeks. I started using the BBB method about a month ago and have turned off my chlorinator. I will have my brother checking in on the house but he does not have a pool and doesn't know anything about maintaining one. My CYA is about 65 and I'm worried about having it increase if I turn it back on while I'm gone. My FC is 6 (following the recomendations on poolcalculator.com) and pH is currently at 7.5. What are my best options for keeping the pool in check while I am gone? Should I just turn the chlorinator on low (like 1/8) and hope for the best or should I try to instruct my brother on testing with my new TF100 kit and adding chemicals as appropriate? Something else?
