Good question.  Only use KNO3 when you have confirmed 0 nitrate with a
SENSITIVE ACCURATE low range test.  Seachem is fine, Sera is marginal.
BTW, again this is an example where a kit can show very tiny amounts, way
off the regular scale, as the faintest hint of color.  But it is there for
sure, you just can't quantify it.

Now, I will be selling KNO3, and way cheaper than your local garden shop
($6 per pound around here).  It will cost $2 per pound, plus $3 shipping,
packing and handling.   So get your friends together for a bulk order.
Have fun!    Dave
