Well, I've been working on this almost a year and finally got my 20G long frag tank up and going. Most of the time was spent building the stand. I used 2x4 and 2x6 frame with pine finish sides, top, and trim this time (it cost half what red oak does). The the rest of the delay was while it set around a few months waiting for me to finish staining and finishing it. It's been set up and running about 10 days with a 2-pound chunk of live rock. Ammonia is still 0.5 ppm so it isn't quite ready yet. I have two HOB filters (one with sponge and one for carbon), 4xT5HO bulbs, and a titanium heater (with external thermostat). Here is a photo. More to follow as more interesting stuff develops. Feel free to offer advice.
