Dowflake Xtra and Randy's 2-Part
 

The original formula from Randy is to use 500grams/Gallon of Dow Flake, which is/was 77-80% pure Calcium Chloride
The new stuff is Dowflake Xtra and is 83-87% pure

Because of it's higher concentration, it's been recommended to use 8% less of the Xtra version, so 460grams/Gallon

If you're using the new Xtra version, how much are you mixing ?

I actually mix a slightly higher concentration for both cal and alk so I don't have to dose as much. Just make sure the two are balanced.

So you use Dowflake Xtra ?

Where can you buy dow flake?

I use a different brand pellet that is 93 to 97% so by weight its even more concentrated.

Obviously you're having no issues then
Thanks

I ordered a 20KG bag through my local Home Hardware

The stuff I got was through acklands granger. I've been using it for over a year and have dosed over 50 lbs in that time.

Anyone know where I can get dowflake in edmonton?

I have some if you want.
