Calcium

[mwsmith2]

There's a .pdf of the stuff here:

http://www.dow.com/webapps/lit/litor...0.pdf&pdf=true

If I get a moment, I'll look up what the ASTM that they conform to is composed of. I think there's enough info there for me to see if it's a safe product. If you can find a MSDS on "pool type" CaCl, we can compare the two and see how they match up.

Paul,

I noticed both Home Depot and Lowe's carries Calcium Increaser in 5 lb containers for around $7. Not real cheap but will keep you out of the pool store.....

Thanks for the good info. I'll stop in and check it out.

BTW - the PELADOW was $18 for 50 lbs.

I just bought some in the pool section at Lowe's. $6.44 for a 4 pound container. I'm starting off with 24 pounds because my test kit is not showing any Calcium.


33k gallons, Aquarite, vinyl.

BTW -- Agway - carries the Calcium Chloride Flakes (77-80%) $10 for 50lbs (this is 20 cents a pound). I asked them about pool usage -- they indicated a local large water park / pool buys it by the pallet. I added it by mixing small batches in a bucket to disolve the flakes -- worked like a champ just a minute or so to disolve. Now I have some left over to melt ice this winter.


Agway also sells Sodium Bicarbonate (Baking Soda) $8 for 50lbs.

HERE IS THE INFO OFF OF THE DOW WEBSITE FOR POOL AND SPA APPLICATIONS:
http://www.dow.com/calcium/app/poolspa.htm

THEY LIST 2 PRODUCTS FOR THIS USE....
DOWFLAKE AND THEIR ANHYDROUS CALCIUM CHLORIDE MINI-PELLETS!

GUESS DOWFLAKE IS THE WINNER IF YOU DON'T WANT TO BUY IT AT A POOL STORE. I WOULD BET THAT MOST OF THE CALCIUM HARDNESS INCREASER SOLD IN POOL STORES IS JUST REPACKAGED DOWFLAKE!

[mwsmith2]

Cool, cool, that seals it for me. Now if I can only find that stuff.

Try lowes or home depot! I've seen it at one or the other! btw, I just read the Dow pdf on their calcium products
http://www.dow.com/PublishedLiteratu...romPage=GetDoc
and it seems that :
"DOWFLAKE 77–80% process grade
calcium chloride meets or exceeds
Food Chemicals Codex (FCC IV)
monograph for calcium chloride
dihydrate and complies with FDA
Good Manufacturing Guidelines.
It also meets the American Water
Works Association (AWWA) standard
B-550 and is Kosher certified."
I guess that means it's pretty pure! Heck, it's even Kosher!(two of my great aunts used to be cooks in the "Borscht Belt" in the Catskills and I remember them using calcium chloride in the brine when making pickles! So did my mother! I think it was to keep them crisp)
