Okay, got a 10 day trip coming up next month.
Chlorine consumption is about 2 ppm/day. So.... I'll need to add 20 ppm. Are you following? CYA is about 40, so I want to add some more. Some part of the pool is in the sun from about half an hour after sunrise until about half an hour before sunset. 50 or even 60 wouldn't be excessive, IMHO.
Trichlor tablets seem like the way to go. If I add 20 ppm via pucks, I will add 12 ppm CYA, correct? And to add 20 ppm to a 16000 gallon pool will take about three pounds of trichlor. I've seen individually wrapped pucks for sale on the counter at the local pool store. Should I just go buy three pounds worth?
Someone please check the math and tell me, am I right?
