I have had a saltron mini for as long as I’ve had my little “cheap” roto molded tub, 5+ years. I am almost certain it doesn’t have a titanium heating element nor the most robust parts (it has a friction heater/pump) & its still going fine.
My saltron mini cells last about 18 months & it runs about 2/3 hours a day on average in my 250 gal tub. I have had to replace 1 saltron controller box. Currently I have a spare cell but when it dies I think I will switch to a controlOmatic unit. They cost a little more upfront but they seem to have a longer lifespan. They’re only con is that the contoller isn’t supposed to be in the weather so I would need a weatherproof box for it.
The swcg’s main job is standby chlorination. I dose with liquid chlorine or dichlor (if i’m in need of cya) after using the tub for most all but the shortest of soaks. I have mine on a timer, the unit comes on if the power goes off & is then reapplied so the controller is set for 1 hour & the timer is set to remove then reapply power for 2,3, or 4 times a day depending upon the season(whether i’ll be using the tub alot or a little). This allows for a steady level of fc vs a whole bunch at once then nothing. It also means i can just press the controller & turn it on for an extra hour without messing up the rest of my schedule or having to remember to go back & change it.
