So you can get away without macro nutrients assuming you have ow medium light and a decent fish load. Though I would still dose potassium.

But even with the best substrate in the world you will eventually becime micro deficient.

ALL tanks (with very few geographical exceptions) will become deficient in micro-nutrients over time. The first deficiency most see and report in my experience is iron.

whether you add the fertilizer as a liquid or a powder is immaterial. But I would suggest a buying dry unless you like paying for and paying to ship water.

Look up nilocg sale thread for dry ferts. You will be shocked how cheap they are compared to the liquid crap
Nilocg? So are dry fertilizers comparable to what I would get if for example I got anything from ADA? or Pfertz? And when you say dry ferts are you talking about like the kind you insert into the substrate? "root tabs?"
