Ok, I know nuthing about clams, but i am interested in getting a few. I just read that it depents on the spectrum of light, not tha wattage. Is this true? I have 4 55 watt PC @ 9325k each plus 1 20 watt actinics. Is this good enough to keep clams? Tank is 22 inches deep, but i have 4 inch DSB so thats about 18 inches. Also can someone explain spectrums and kelvins, in idiot proof terms?
