Achieving that "perfect" balance…

I was able to get rid of Cyano for a few months with the slime remover product. It was effective. I also used careful dosing of potassium nitrate, which also did a great job. Unfortunately, it's an ingredient used by domestic terrorists in the US, and it's controlled here in its powder form.

Can anyone suggest a fertilizer mix for tanks that is extra high in potassium nitrate?

I see a killifish hiding behind some plants in the back corner of the tank making bombs
