Where in Washington do you live? I'm just getting into CRS myself and recently set up a 10 gallon super low maintenance tank with a single T-8 15 watt bulb. I'm running an AC70 on it! No CO2 and no ferts. It's mostly java moss, java ferns 'Philiphine', some stems, red root floaters and anubias nana petite. If you have a large army of CRS, they will absolutely pick that 10 gallon tank clean in no time! This has been one of the most enjoyable tanks that I've had.
