Calcium chloride

[dtracy1119]

I just picked up some of this at HD. Says it's 94% calcium chloride. Just like Dowflake. The rest is potassium chloride, magnesium chloride and water. Is this ok to use in a mixed reef tank

The magnesium chloride is OK. I'm less sure of the potassium chloride. I didn't see any percentages for any of the ingredients, but if it is 94% calcium chloride, that's good. Do you know the percentages for the other two?

I believe Dowflake is all calcium chloride and water, no potassium chloride or magnesium chloride.

I can't find any percentages but it says it's similar to peladow.

Right next to the calcium chloride it says 94. So I'm guessing it's 94% calcium chloride.

I found the percentages.

What are you using it for?


Might be okay for the occasional tweet of calcium. Might not be a good choice for two part. The problem is a potential accumulation of potassium. I mention this because our tanks generally consume calcium at a rate greater than the ratio of calcium to potassium indicated on the bag’s label.

I used to use Prestone driveway heat. I scooped up MSDS (before they got renamed SDS ).

Here it is. Looks kinda like the HD Heat labeled you shared above. This one gives a % of potassium chloride.

Was planning on using it as the calcium supplement.

The SDS you shared in post #5 does not mention potassium. Is it for the bag of heat you are inquiring about?

Ewe not a good sign when the SDS lists NaCl2. What is that? I wonder if the KCl is being coyly covered under the banner of alkali chlorides.

I’ve been using prestone driveway heat for a few years now but have thought about switching. No obvious problems so far though. Following along...

Yes. The pellets of heat bag on the front says there is potassium chloride.

Using it for adjustments (like me) or for regular 2-part additions like the OP wants to?

Just a comment. I've been using Dowflake for CaCl and Mag Flake for MgCl for almost 10 years now with no issues. I also use soda ash from a pool supply store for alk and Epsom Salt for Mg sulfide. I've had an sps tank and a zoa & RFA tank and both were healthy and grew fast enough that I had to do a lot of fraging. I started with 6 RFA's and after 3 rounds of spawning I now have abot 35 of them. So I think it's pretty safe.
