I seem to remember reading that potassium is taken up slowly, so once you get it to NSW levels it is easy to maintain, but getting it there takes a lot. If this is the case, maybe it's time to change the salt. *gasp*

PIF I'm guessing is the potassium iodide fluoride, there's also K-Balance with is just a potassium supplement. I use both and find they last a long time, yes they are more money than other types but check the dosage rate. Usually other supplements are 5ml per 25gal while zeovit is 1 drop per 25 gal so more often than not zeovit is the better value. I also like the higher concentrations for the fact that your putting less unknown substances in the tank and I simply trust zeovit over other brands so even if it does cost a little more I don't mind. Same goes for the RB salt, it costs more but you'll dose less and possibly even save a little money.

You don't want to use PIF to maintain K+ levels. You'll overdose with iodide before you hit 380 ppm. K Balance Strong is the way to go.
