Diy Calcium chloride

[USMA36]

forgive me if this has been asked but will this particular brand of food grade. Alcuin chloride work for diy calcium solution? It says food grade 97% but does not say what the other 3% is. Earthborn Elements Calcium Chloride (1 Gallon), Wine & Cheese Making, Food Additive & Preservative https://a.co/d/fUGQb7J

how about regular Prestone or similar calcium chloride driveway melt. Is that pure enough and without contaminants that will harm a reef?

I stopped doing anything less than USP grade for additives due to the mix coming up brown and merky.
I always try to find the SDS before using anything.

That food grade one should be fine but
I would spend the $10 extra for 7lbs of BRS usp grade calcium chloride to ensure theres no anti caking agents.

The earthborn elements is what i have been using the past 1-2 months or so. It’s been fine, I will say that it does have some white powder that settles (I believe it is calcium carbonate). I just ignore it.

Food grade is just fine. Most of the 3% is water.

I think mostly the caking agent caused the brown and merky water.

I'm not convinced there is any anticaking agent used in food grade calcium chloride. Simple bottled chemicals do not ordinarily contain additives, just impurities.

I also am not aware that USP grade has higher specs than food grade.

@Randy Holmes-Farley - do I use the same amount as your two part recipe for the Earthborne?

I’ve been mixing it following the recipe, but anhydrous. (Use 20% less or 400 grams instead of 500g)

Boring-I was hoping to see someone mixing metallic calcium and chlorine gas or something...

Outside my ballsy skill set currently.

The reaction between calcium (symbol ) and diatomic chlorine gas C l 2 to give calcium chloride ( C a C l 2 ) is shown below: C a ( s ) + C l 2 ( g ) → C a C l 2 ( s ) . As it is written, this equation is already balanced.

I cannot tell if it is anhydrous or a hydrate from the descriptions I read. The 100% comment is not necessarily revealing in that regard.

If it gets hot when it gets wet, it is anhydrous. If not, it is the hydrate.

Mixing at 500Gs if it does one or the other, is there something I should do differently or is it fine as it and this is just informational? If I recall correctly the stuff from BRS is anhydrous.

If it is anhydrous, it will be a bit extra potent and 1:1 dosing will be off, but that’s ok if you understand it.
