Diferent Circupool Models output?

Well, honestly when I ran my numbers it was slightly more expensive over the life of the first cell at the time versus bleach. Bleach was slightly cheaper than a water change at Tucson rates which are some of the highest anywhere. The next cell was cheaper by a fair bit... So it does have a payback but I actually suspect I won't be still living here when that occurs.

But everything has changed since then and the whole thing needs to be redone. I have serval neighbors to dump slight more than half their water at CYA=100 and swear it's the cheapest way. I do like the way salt feels and there is the PITA factor in having to do this. In areas where you might need to worry about floating your pool (not here) then that potentially means a series of water changes, but at cheaper rates...

With the increase in the cell, that $20 or so pushes it up a year...

My CH in the fill water is so high that I probably will need to do a water change at about year four anyway and I didn't figure that in the calculations. So honestly, despite what everyone says here, I suspect it's always going to be slightly more expensive to do a SWCG. Overall it's pretty nice though except for the increased acid demand. I am very happy I made it to 12/16 before it shut down. I for the last two days I've been able to restart it at noon time... so it's an 10.5-11 month device here in Tucson...

Between tablets and liquid chlorine, I also found that tablets + draining pool is a lot less work, and cost less $ than lugging liquid chlorine + a lot of acid to reduce PH/TA. my fill water has TA 160 and high pH.
Hopefully SWG works better than those 2 methods, we shall see.

I like the way the water feels vs liquid or tablets.
I do agree if SWG go up a lot more they will loose market share..

Maybe the folks that make tablets are buying all the metals to force us to buy thier product

EV buyers are not as price sensitive as SWCG buyers.

The price of Ruthenium has gone up 20% in the past 15 days and the price of Iridium has gone up 200% in the past 60 days. This is on top of the 200% price increase of Ru in 2019-2020. Since the coating on salt cell plates is about 6:1 Ruthenium/Iridium this translates into MUCH higher prices for salt cell in 2021 IMO .

Reason given for recent Ir price increase is supplies from mines in South Africa has essentially been shut off due to variant Covid strain originating there. Do prices return to norm later in the year or will they only retrace a little?
