The calcium chloride for the two part

[Curtis Thigpen Jr]

Hey Randy I just wanted to know if this Dow flakes is sufficient enough to use for the calcium part of the two part

 

[Randy Holmes-Farley]

Yes, that looks good. use 10% less volume than my recipe.

 

[Curtis Thigpen Jr]

Ok thank you

 

[Randy Holmes-Farley]

You're welcome.

Happy Reefing.

I'm no chemist and my "gut feel" is dr holmes-farley is right on.
above is from product data sheet.
looks like nacl (salt) can be up to 6% and magnesium chloride is greater than .5%. both of which should be no problem.
Calcium hydroxide is kalk and at high concentrations can be a problem which is why we drip it. But should not be a problem as lower concentrations.

Perhaps dr Homes-Farley can provide more insite but then the good dr probably checked this out already.
