Due to the increasing uncertainty in finding liquid chlorine, I finally decided to invest in a SWGC. After reading a ton of threads on this forum, I settled on the Circupool RJ60+ from DSP. I'm planning on installing this weekend and would like some help double-checking my calculations for setting the % generation on the SWGC.
Based on some other threads (mainly this one: Lbs per day to gallons of chlorine, and run times, electrical costs?), it appears as if one lb of chlorine generated from a SWGC equates to 1 gallon of 12% liquid chlorine. For an 18k gallon pool, I calculate the FC chlorine production as follows:
3.1 lbs 1 gal 12% 6.7 ppm FC
------- x --------- x ---------- = 20.7 ppm FC / day produced
day 1 lb 1 gal 12%
My pool typically consumes about 3 ppm of FC per day, so dividing the 3 by 20.7 means I need to generate 14% of the capacity of the RJ60+ per day. I can either run the cell at 100% for ~3.5 hours or run the cell at 14% for 24 hours (and any point in between those two extremes). I run my VS pump 24/7, so I'm planning on running the cell for 14% for 24 hours to have a more consistent generation of FC throughout the day.
Does all of this math look correct?
Of course, I will measure and check the FC level daily for the first couple weeks to make sure the generation is correct, but I was trying to find a starting point that would be close to correct.
