my whole family is going vacationing for 2 weeks.
Usual question, what do we do about the pool?
So far my FC decline rate is under 1 ppm a day due to a fairly high CYA = 77.
So when I dump a gallon of it at 8.2% strength into the pool (26K gallons), three days after I still read between 5 and 6ppm.
Now if I dump a whole lit of it, the devline rate will increase as it is dependent (I think exponentially) on the init qty, so I am not sure if this is a good solution.
I could possibly temporarily revert to tab clorination (I have an in line chlorinator still though it is empty) but then it will raise my CYA which I think is higher than I'd like in the 1st place.
I wonder by how much it would raise it, if by 4-5 ppm over two weeks, I can take that but I fon't know that.
Any other good practical way? Short of asking neighbors?
