Changing my daughter's 5 gallon Hex to a planted tonight. Put a thin layer of peat then a 2" layer of pool filter sand. Replaced the bulb to a 10 watt CFL 6500K Daylight Bulb from Petco. What kind of light will this tank be? I am assuming low light? Haven't filled it yet because I'm not sure I am satisfied with what I've done so far.
