what to use to make soft water a little harder

I am just wondering what is a good thing to use to make soft water harder?
I remember reading it somewhere but can't seem to find it now.
Thanks

Baking soda will raise kH.

Calcium chloride and magnesium sulfate will raise gH.

Dosing directions can be found in my Guide. Read them first as baking soda is extremely powerful.

Wal*Mart.

Magnesium Sulfate is more commonly known as Epsom Salts.

Calcium chloride can be found in the ice melter, the RV dehumidifiers, and one other place that I can't remember right now.

You can find calcium chloride in pool/spa supply stores. Some of the big box stores that sell pools (inflatable or above-ground types) will have the stuff seasonally as well.

I put cuttle bone (it's mostly calcium carbonate) in my tank. Acid water dissolves it and keeps my 0 kh water at a more reasonable level. What's best is that it dissolves as needed. In fact, I've even seen my rubber lip eat it, like a salt lick.

In addition to the others mentioned; Seachem's Equilibrium will raise GH also. Equilibirum Also, Barr's GH Booster will work. Dry Fertilizers

what about putting...i think it's natural peat moss in a nylon, rinsing it out, and hanging it in your filter outflow, i always heard that would buffer your pH.
