Hey Silva !!!
*cracks knuckles and gets ready to count beans*
It looks like you have a timer instead if automation so we can shop around for a brand. If automation is on the horizon in the next 7 years or so, you'll want to go with that brand here too.
So in Houston you have a long and hot season. A SWG rated for your volume would need to run 24/7 to produce enough FC during the peak season. A 2X unit makes the same FC in 12 hours, not only saving pump electricity but then doubling the lifespan of the SWG. A 3x only needs 8 hours runtime, tripling the life.
I'd go 3X in NY in a heartbeat, and 4X if I lived in a hot climate. The ROI pays spades going larger. It's a little more expensive for lots more life.
So let's crunch a Circupool RJ45+ for a 3X unit. It'll produce 17 FC per 24 hours, or 7083 lifetime FC. I estimate way low because they claim the produce 50% more for 50% longer. So I use their FC claims at 10k hours instead of 15k hours. It could do even better than I'm calculating but want to err on the side of reality.
It's $1295 (with tax) for 7083 FC, or 18 cents per FC. Let's double the cost to allow $1295 to pay someone to install it and it's going to cost you 36 cents per FC, or less. Future cells don't need the controller or the install and may approach 10 cents per FC.
1 gal of 10% chlorine gets you 7 FC.
$4 jug = 57 cents per FC
$5 jug = 71 cents per FC
$6 jug = 85 cents per FC (Walmart is $6.12)
$7 jug = $1 per FC (Lowes is $7+)
$8 jug = just don't.
So even if you have a steal of a deal with $4 bleach, it's 1.6 times more expensive to lug jugs, if you paid through the nose for a pro install of a RJ45+. Future cells would utterly spank the $4 bleach saving somewhere near 5X.
The RJ45+ will save you lugging 1011 jugs, and I cannot, even begin, to scratch the surface on that convienence. That's worth paying considerably *more* for, but you will *save* and not lug 1011 jugs.
Also for comparison, Walmart jugs which many use, would cost $6187.33 including tax, compared to the $1295 RJ45+. That leaves you a honking window to pay for install and still clean up if using WM bleach.
