dow flake calcium chloride is only in bulk?

[Hightower]

Talked to dow chemical, which brands thier calcium chloride with Univar in richmond. The only distributors appears to be ideal pool and spa which sells a 50lb bag for 38$

Anywhere else you can get smaller quantities? that will take me forever to go through. Unless someone wants to split it.

Purpose in randy holmes 2 part recipe for calcium addition.
