Calcium Chloride in Ice melt

[rashr]

I have recently aquired a 50 lb bag of calcium chloride that was used at our site for ice melt. It says it is 80% with the remaining 20 % being magnesium cholride (10%) sodium chloride, potassium chloride. Can I use this to help keep up my calcium levels in my tank with out danger? Seeing as all of the above are needed I didn't see where it would hurt anything, but I am always just wary if it doesn't come from a fish store. I now use magnesium chloride from an ice melt and baking soda for my alkalinity (both scared me at first). I know what they (fish stores) use is what we can find at the grocery and hardware store allot of times, but it still scares me some knowing my investment is in my hands and they are shaking! Any help would be helpful!

Sure you can use it I do and have mine is just a bit more Prue then Dow flakes are .. As for your Buffer mix the baking soda at a rate of 4 parts Backing soda to 1 part 20 mule team Laundry booster mix it well the borate will keep P.H from spiking really face and will help hold it more steady.. Sea water Carbonates are arrived at from 3 to 5% borate.. Thats mix is what you pay sea chem or Kent's reef buffer 10 X's more for,,
Believe it or not there was a time we had to mix all of our own natural elements for our own use. Like Strontium Carbonate or to Molybdenum (: to even the very salt we use .. People today just think its all new and has to have a fancy label or brand name on it LOL I remember telling gus about using Pickling lime or Quick lime for they Kalkwasser LOL and or adding simple old cheap Dolomite to a calcium reactor to raise magnesium naturally .

Can I use this to help keep up my calcium levels in my tank with out danger?

CaCl2: in itself will raise Ca
MgCl2: in itself will raise Mg
NaCl: in itself will raise the salinity
KCl: saturated keeps the chloride constant
CI: the common denominator

all of those seperate will work depending on the circumstances but there are chemicals added to aid in the melting process. to much CI in a reef tank is not good

but it still scares me some knowing my investment is in my hands and they are shaking!

do what you will, but i wouldnt
