Here’s a thought experiment:
Say one typically loses 3ppm a day to UV. Say the CYA is at 50, which suggests a min FC of 4, with an optimal 6-8. Which is the better system:
1) Run the SWG during the day, maintaining a steady appropriate FC level of say 6, and turning it off at night (when the FC shouldn’t decrease),
-OR-
2) Run the SWG run at night (when some places have lower electricity rates), bringing the FC, say, to 8 by the morning, letting that evaporate to 5 by the evening, and then having the SWG resupply it to 8.
I suppose the main question is: Is there anything significantly detrimental to swinging between 5 and 8 vs keeping things somewhat steady at 6 that would outweigh the potential savings running the SWG at night?
