For example if it states 1 drop per 25gal daily I would assume this is for a fully stocked high demand system, if you have a medium demand system you would dose half.

Well... no. PIF is a color refining product that has little of no capability of maintaining any significant levels of K+. The biggest problem with trying to achieve any form of K+ dosing with PIF is that it WILL result in an overdose of Iodide. You're better off doing water changes with a salt that has elevated levels of K+.

That said, PIF is untouchable for producing vivid blue coloration.
