I couldn't agree more with Mike! I have two low-tech tanks, a 110 gallon with
about 1 W/gallon of light and a 20-long gallon with about 2 W/gallon. The
plants on the big tank grow like weeds, including some species that are
supposed to "require" high light. If I had to do more prunning it would not
be an enjoyable hobby.
The small tank is just getting started, but it's starting to look nice too.
