Questions - Need some input

I am going to try zeovit system on a 100 gallon tank. I want the dosing of zeovit additives to be fully automatically. The problem is that I am supposed to dose in drops (1-2-3 drops), and the min dosing amount of any dosing pump I saw was around 1ml (which roughly 20 times more than 1 drop). Is there any pump on the market which can produce just a drop? Does anybody know if it is possible to prepare a less concentrated solution of Zeovit additives?
