I'm trying to build a case to get the camp I work for to invest in a SWG system for our pool here in the middle of the desert. Currently, I'm experiencing about 4ppm of FC loss per day (from about 9 after adding down to about 5), which given the pool's volume of 25,000 gallons, equates to about one gallon of 10% bleach per day. My cyanuric acid is at 60 and the pool gets lots and lots of sun, so as far as I know, that's not an unreasonable amount of FC loss this time of year. I have ordered the FAS-DPD reagents for my Taylor test kit so I can perform an overnight FC loss test to know for sure, but at this point I'm going to assume it's just the sun.
With bleach costing about $4-5 per gallon, and the pool running year round, even if I assume an average daily bleach cost of $3 because of less sun during the winter, I'm getting about $1,000 in chlorine cost each year using liquid chlorine. A 60k SWG is not too much more than that, and should be able to last 5+ years before the cartridge needs to be replaced, which is even less. That seems like an awfully large cost benefit from switching to SWG, which seems contrary to what I've read here which is that it's usually about a wash.
I'm completely aware of all of the convenience reasons for switching to SWG, I just want to get some second opinions on my estimated cost since it seems to be quite a bit different than what I've read in other places on the forum. Another thing worth noting is that my pump is already running 24 hours per day, so the added pump run time will not affect the cost in any way.
