Potassium plan ferts that are store bought can be really expensive. $6+ for just a month supply.

I noticed that some Salt Substitutes are nearly pure Potassium Chloride with some other minuscule non toxic calcium additives. This stuff is nearly pure KCl and I'm wondering if this can be used as an inexpensive potassium plan supplement in an aquarium?

Any concerns in doing this?

**EDIT**
Flourish Excel derives potassium from Potassium Chloride so I guess I answered part of my own question.
Has anyone done this before?

Sleeve,
Yes most salt substitutes(KCl) will work as a source of K as well as KCl used in water softener systems...

I prefer K2SO4 which can be obtained from Greg Watson along with any other ferts you may want/need.
