I have a 13,000 gal gunite pool, with a SWG. I'm using the ColorQ test kit, and just had it opened for the sprint. I have done a few adjustments, and know have the following readings:
CYA: 40 (need to bring up to 70)
Temp: 45 F
According to The Pool Calculator, my CSI is alarmingly low, I guess largely due to the temp. If I bring the temp up to the 70's, it's better, although still close to the lower limit. No plans on using the pool for a few weeks, so I hadn't intended on heating it yet. However, now that I see the CSI, I'm wondering if it's doing damage to keep it at these levels for that much time. Do I need to start maintaining a min temp to prevent damage? Or should I not worry about it? Or, is there some other water parameter I should change?
Thanks in advance for any advice!!
