    Thanks!

    Well, considering that I did add 0.4 percent iscaguard PEG and 2% tocopherol with the geogard ect(benzyl alcohol, sorbic acid and salicylic acid), and my ph is 5.1-5.4 (using precision test strips), should I still be scared? The batch will be used up in a month or two anyway.

    The Geogard line seems to have a wide variety of products, with differing active ingredients. Are they all useless, or would geogard ultra(Na benzoate gluconolactone) work better?
