I am trying to finish up this 20 gallon viv to eventually house some incoming R. variabilis. It's the first real one I've put together, and I could really benefit from the amount of experience represented by the members of this forum!
It's using clay for the 3-sided background and I've got a tube embedded in it which will be used to feed the smaller siphon tube down to the false bottom under the gravel. Misting will be done via one 1/2 inch Mist King nozzle.
Up high I've got two mini orchids and a brom. On the floor there's the pepperomia, begonia, a jewel orchid, one brom, and a couple other misc things small pieces.
Now come the questions:
First of all, could these plants and this arrangement work well?
What kind of lighting requirements would be needed for these plants in a small tank like this?
How about air circulation needs? How much airflow or cfm is necessary? This seems like the toughest issue for me. With the 19.5 by 9.5 top, cutting vents for external circulation in addition to the two holes needed for misting and drainage seems like it would be crowding things. I was hoping to do a hinged lid with nothing drilled in the front 5 inches so I can lift it up for feeding. That leaves a 19.5 by 4.5 inch strip to work with. Is there a reasonably easy internal circulation solution you'd recommend? Maybe something like this: http://www.dendroboard.com/forum/par...rculation.html
. That thread doesn't mention what tank sizes it is good for.
