Dowflake Xtra and Randy's 2-Part

[gregzz4]

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.

[gregzz4]

So you use Dowflake Xtra ?

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.

I have some if you want.

[gregzz4]

Anyone else using the Xtra stuff ?

Any issues in keeping Alk and Ca balanced with the higher purity ?

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