Calcium Cloride / Peladow

bkhunt · Feb 20, 2015

I have heard that Peladow can be used and that it can not be used as the calcium part of 2 part dosing. I currently use baked baking soda for my alkalinity. If it can be used are the photos below the proper product? What would the proper mixing ratio be per gallon of RO/DI water?

Peladow is an anhydrous form, so you only need 2 cups of Peladow made up to one gallon of RO/DI (Recipe 1). Here's Randy's recipe.

Lilbuddha, that reference you have is when Randy was young and foolish. The one I've included is the "improved" two part when he was much smarter. :yo:

I though it was anhydrous calcium chloride also but the ingredients also list sodium chloride and potassium chloride also.

Could be OK but that makes me nervious.

Check with your local redimix companies for pure(er) calcium chloride. I got a 25 pound bag of cal-chlor (I think) which is anhydrous 96% calcium chloride for $8 or so.

I just bought it to use on my sidewalks and said hey that I the same stuff I use for the aquarium. I was doing some reading today and saw where people said yes and were people said no. I figured I would just as here and see what people said.

Again, if you go back to the Randy reference I have above, you will see he references Peladow. In looking at the MSDS's of Peladow and Prestone Driveway Heat....the one I use.....you will see they are pretty much the same concentrations of other stuff.

Assuming it is still made from the same material it was in the past, the concern is that the process changed a few years ago by Dow, leaving more bromide in the salt mix. The potassium and sodium chlorides are not a concern, and actually make it better for this purpose (at least the potassium). With water changes, the bromide issue is reduced, and may be fine, but it is not as optimal as it was years ago.
