Correct. It's much cheaper than buying excel.
I bought my kno3 online, but I've read that spectracide stump remover is pure kno3 also. Just google around a bit.
The cost isnt too high form a place like aquariumfertilizer.com or bobstropicalplants.com, as you'll likely need to get the rest of the macros/micros anyhow and might as well get them all at once. The one exception is mgso4 which is easily found in its hydrated form in basic epsom salt.
