Question for those using repcal and herptivite

[AncientCritters]

My wife bought some shakers for me to use and put the calcium in one shaker and herptivite in the other. SHE DIDNT LABEL THEM . One is a grey color and the other is more yellow. Which is which. THanks for the help.

herptivite is a finer powder and yellow. Repcal is white-grayish and a little chunkier than herptivite.
