Sad story... I had to leave my pool for 32 days unattended. I'm new to the area and know no one that could look after the pool. The trip was sudden and no time to hire a service even if I thought I could trust one.
When I left my numbers were:
I installed an auto fill I made from a toilet float, and made a guess at setting the timer to 5hrs a day and the SWG to 100% to allow for expected hotter weather. Dropped in my MX8 Pool cleaner and crossed my fingers.
Happy Story... On my return 32 days later I found A skimmer full of leaves, a leaf canister with lots of bugs and debris. AND:
Let the FC drift down below 10 and confirmed PH then two small doses of MA per pool math to get the PH to 7.4, installed my fountain to cool the pool a bit, and a little clean up. That's it. I had my pool in swimming condition with full confidence that it was truly safe by noon the next day after 32 days of no attendance, testing, etc. I'm lucky that I don't have a big leaf or debris problem and that helped make this possible.
Thank you all for your help in teaching me a complete beginner how to take a pool that had been closed for quite some time full of tadpoles & frogs to the sparkling oasis that we have now. Everyone's answers have been patient and understanding of my novice pool experience. The small donation to become a supporter is SO worth it!
