You need to provide a nice range of nutrients for plants in order for
them to grow well, not too low= algae, not too high= dead fish from
very high NO3(100ppm or more using KNO3)
====================
Not everyone knows what you're talking about. Not being a chemist, I have
no idea what the above are. And not everyone can afford a large number of
tests kits. So we tend to stick to the plants that thrive for us with a
minimum of supplements.
