kent marine nano part a/b (http://www.marinedepot.com/md_viewItem.asp?idproduct=KM3521)
also, do i just go by the directions? or is there a way to measure how much i need to add after obtaining my test results.

I hope it's a good product, I just ordered it and got it yesterday.

You'll need a CA and an ALK test kit, no way to know how much to add without one.

yeah, i have the kits. i was just wondering whether or not i needed to go by the directions or just test before dosing because the directions don't know my starting values.
