You are WAY OFF on this calculation. you said your rate was 16c/kw-hr.
.4kw*12 hrs = 4.8 kw-hr's
4.8 kw-hrs*16c = 77 cents /day
.77 cents/day *31 = 23.87/month
You already figured out that the water is negligible.
Salt - The most expensive salt I can find is $90/200 gal
bucket doing 60 gal
changes on a 300 gal
tank every 2 weeks (that is a lot...probably over kill) that is about $60 a month.
The cost to run a tank is just not that much If you are changing that much water you won't need to suppliment anything.
