SNAP system question

My husband and I finished installing an 18' above ground a couple of weeks ago. :D Thanks to this forum I have only added bleach and a few tri chlor pucks to the water until I get my CYA to good level. My question is that the pool package we bought came with the "SNAP system" of pool care. I know what the clarifier and tabs are, but I was wondering if anyone could tell me what the bottles of "initiator" are for. :confused: The instructions were to add it when you filled the pool, but nowhere on the label can I find the ingredients listed and I just haven't gotten around to calling the company. I would rather have the opinion of the experienced pool owners from this site, anyhow. I have learned so much from this site! The information posted here helped me defeat a mucky, dark green, tadpole infested pool of my mother's. Thank you so much for such a wonderful forum!

Apparently we 're both gonna have to wait until someone knows about this stuff.

I tried to find out by looking at Gaurdex's web site. Like you already know , it doesnt give anything on what it is. When I saw the link for the MSDS , I thought good that'll lay it out. THe link was dead...things that make you say
"hmmmmm" ...I dont know

I know bleach , baking soda & borax though ;)
