Anyone use Randy's 2 part calcium additive?

Just wondering if anyone has experimented with Randy's 2 part calcium/alkalinity additive, and what results have you seen?

have used it and it is very easy and inexpensive. Though my calc/alk consumption is fairly low (slowly growing as i add more and more sps frags ) it has lasted me about 2 months for one batch. I give it

Do you have a link for this product? My 2-part is running out and I need some more... hopefully cheaper stuff.

I use it for when I haven't been able to drip the limewater at night and for the fish sitter to use as I don't want to have limewater accidents while I'm away.
I had to make it a full 3 part formula so that I dose equal amounts of the calcium, the alk, and the epsom salts.
The original formual says to dose a given quantity of epsom salts after going through a given amount of the 2 part formula, but with multiple systems on the go, (7) I have no way to reasonably keep track of how much of the 2 part goes into each individual tank as they are differing in volume as well as needs for the additive.
Worked out easier to just use 3 parts every time I dose.
