His article was like a breath of fresh air for me.
Instead of starting with a formula and tuning it to your particular tank requirements (e.g. Estimative Index), you get to find the formula via a series of very simple iterations, starting with NO3, then PO4, then Mg and Ca (assuming you have sufficient CO2 and proper lighting).
It is a particularly attractive methodology for beginners (me!) having a hard time dialing in to proper fertilization.
Whether you are an expert or a newbie, I think it is definitely worth a read.
It is definitely a good read. For most beginners though, this would seem like an excessively time consuming process (weeks between each compound in some cases).
I would think most new planted tank owners won't have the patience to see to the finish.
Ultimately, there's no one perfect way to run your tank. If MCI works or you prefer EI or just eyeballing it, if you are happy with your outcome its all good.
Interesting, I actually thought this was more beginner-oriented than starting with an E.I. formula and then [slowly] adjusting it to my particular tank.
I've been using ferts for almost a year now and I'm still not very good at judging what is lacking and what is in excess. I'd be glad to find a good balance in only a few weeks :P
