hahaha yeah i google it already, seems like the light is turning green very soon, a lot of ppl seem to be doing it and nothing bad so far, and even Randy said it might be ok now. I would love to get some Magflake from you, but your not in Calgary.

Wallmart
 

I get mine from wallmart :biggrin: If you go looking though enough of the ice melts you can usually find one that is just a bucket of mag-chloride and nothnig else (except probably a little contaminate) but I have been using it for about 1 year now without trouble. and 20lbs is about $6.

I also hit the pool place for my dowflake. It's used to increase calcium hardness in pools. Somewhere about $4-$6 per lbs.
I can always find calcium chloride in the driveway-melt. But they always add urea and other colorants :sad:

walmart
 

man oh man, what else doesn't walmart have these days???
maybe they will bring back the fish department and bring in marine fish too.

But thanks for the info, i'll go look into that too.
