I am playing with the idea of setting up a ~2G nano for my office at work. I have a 2 or 2.2G hex acrylic tank that used to be my wife's goldfish execution chamber. The tank originally came with an
undergravel filter (long gone) and a 15 watt light. Obviously for any marine tank waterflow is important. Yet in looking at power heads the flow rates on even the smallest units would be astronomical for this little tank. Considering the hex shape I feel even the smallest power heads would make this tank look like a toilet flushing. What would be recommended for a descent but controlled water flow? I remember seeing some micro power filters a while back, but the hood would not be compatible with such an item.
Also, what putting one of those 10W full spectrum flourescent retrofit bulbs in the hood? This comes up to 5W per gallon of light in what I believe is a PC bulb. For a tank that is probably 10" tall is this sufficient for something like a zoo or mushroom? It doesn't seem like much light, but this isn't much of a tank either.
