I know I'm way late to this party but I caved on the cyber-Monday sales and picked up a 6 gallon Edge(21LED) for my desk. It literally took me three days to read this entire thread
I'm planning a fairly simple setup(I hope). It will be my first attempt at something similar to an Iwagumi layout. Still trying to figure out where to find some nice looking stone. Seiryu or maybe petrified wood if I can find either. Suggestions on a source are welcome.
I will be using the stock filter(I use the same thing on my 10 gallon QT tanks and am comfortable with it's ability and maintenance.
I was thinking of getting the light bar for the 12 gallo(42LED) but from the sound of it this may not be a worthwhile upgrade. Twice as much light in the center and little or no improvement in coverage toward the outside.
I'm planning on doing it low tech(at least that's my plan) with a carpet of Marsilea Minuta and possibly nothing else. Alternatively maybe some DHG or microsword in the backround and maybe some sort of dwarf crypts in the corners to help make them dissappear, although I don't think that fits in with the spartan nature of Iwagumi. Again suggestions are welcome.
I'm thinking of using one of those Hydor mini 15W heaters. I like the idea of stuffing it in the filter to not have anything extra in the tank, but was also considering burying it under the substrate(kind of like radiant flooring taking advantage of the thermal mass of the substrate). Not sure if it's enough of a heater though as the house stays in the low 60's in the winter.
Speaking of substrate; was looking at using Fluval Stratum maybe with some MGOPS under it to help keep the plants going.
For stock I'm planning on keeping it simple;
Thai micro crabs
and maybe.....just maybe a small school of Pseudomugil gertrudae(I have six in a 20L that I'd like to tear down and use for something else.
I'll post pictures once I get it scaped.
