Average Salt Amount Needed and Normal Water Level In Brine Tank
Last Updated: 03/16/2014
The amount of salt needed to properly recharge a water softener is mostly based on the amount of resins being recharged.
3/4 cu.ft. resin = 6 - 9 lbs.
1 cu.ft. resin = 8 - 10 lbs.
1.5 cu.ft resin = 12 - 15 lbs.
So, an average residential system will use 6 - 12 lbs of salt per regeneration at least once a week. Very hard water, or water high in iron, may require regenerating every 2 or 3 days. The result is you will be using at least 30 - 40 lbs. of salt per month if hardness is not too high, or amount of water used low.
P.S. If you run out of Salt, don't expect to have soft water after a few days. And it may take more than one regeneration to get the water feeling soft again once you've added salt.
I recommend keeping the salt level above the water level in your Brine Tank.
When you start seeing the water level ( normally between 6 - 12 inches ) then it's time to think about adding more salt ( 40 - 120 lbs. ).
Does it matter which type of salt is used? Pellets or solar salt crystals? Is one better than the other?
Either will work.
Recommend the solar salt crystals as they dissolve 100%, as opposed to the Pellets that leave an un-dissolved residue in the bottom of the brine tank. And this residue builds up until it clogs the flow of the brine water in and especially, out of the salt tank, requiring that the tank be dumped, emptied, and re-filled with new salt ( plus 4 gallons new water ) every 1 - 2 years on average.
In simplest terms:
