As a dedicated low-tech planted tank enthusiast, my main objection to this set of articles is that Chuck makes like the only way to go with planted aquaria is the high-tech approach, including expensive substrates, precise fertilization, and CO2 injection. There are quite a few people, including myself, who grow lots of healthy plants with exceedingly cheap substrates (cheap soil + cheap gravel), no CO2 injection, and no ferts. The main thing that the low-tech and high-tech approach have in common is that they both requre good lighting -- a bit less with low-tech (2WPG is a good amount), but still far more than you'll get on a stock tank.
As a counterbalance, I invite anyone who reads Chuck's web pages to also read this:
