Potassium in water softener

[tysfamily]

I don't know if I'm in the right spot, if not please direct me there. I was wondering if anyone has any idea about Potassium Sulfate. I use it in my water softener instead of salt. My kids hate the taste of the water when I use salt. So I use the Potassium, but I have a 5 stage RO/DI for the saltwater tank.

Does anyone know if the potassium will pose a threat or will the RO get it out? I don't want to kill anything or have some weird crap growing all over my tank.

Thank folks for the help.

I use Potassium Cloride all the time in my water softener for the same reasons. I have not had any problems with or without using a RO unit for the last year. The amount of potassium that is introduced to the water is very small. And a RO/DI should remove 99% of what is introduced into the water.

I have never heard of using Potassium Sulfate. Are you sure it isn't Potassium Cloride? Potassium Sulfate is usually used as a fertalizer.

Heck I'm not sure, I just took a gess. I just buy the white bag at Wal Mart and I do know that it's Potassium. I wasn't sure if it was Sulfate or Chloride. So I looked in the dictionary and sulfate said that it was a salt and the chloride was a form of chlorine. So I just went with sulfate. My bad, I figured that I was taking the chlorine out of the water not putting more in.

It's potassium chloride. I get the same stuff from Walmart too. It's not putting any more chlorine in the water or removing any chlorine. A water softener removes Calcium and Magnesium ions from the water, replacing them with either sodium or potassium ions. This make the water soft, giving it a general hardness of usually less than 5 and reducing the KH in the water to less than 5 also. This may vary depending on whether you have city water or well water and where you live. But you should see a very marked reduction of both KH and general hardness of you water.
