I bought a display tank off Craigslist that a guy had intended to use as a frag tank. The dimensions are 69.5 inches long x 13 x 12.5. It has dividers separating it into 4 smaller tanks and 1 long tank, but it is all connected, 69.5 inches long.
I want to use this for plants only. I have been using plants in my tanks for about a year, and I think I find them almost as satisfying to raise as the fish! I thought it would be fun to experiment with a different kind of substrates, different water hardnesses (if each tank really is separated from the others), vary the lights, and, of course, try all kinds of plants.
Has anyone ever tried this? What are some of the plants you found most satisfying or surprising? Any ideas of what other factors I could use to experiment with or types of substrates, etc.?
