well at the lfs today i bought the power glo light bulb its for my 20 gal tank and it is 15 watt 18 inch(no higher wattage) it also has 18,000 k, would this be a good bulb for my tank? it was from 18000 to 2800 k and so i got the 18000 what does k really mean and what is good?
it also says good for african chiclid tank, high blue spectrum and lux of 55
is 18000 to much becuase i read in the sticky that plants use between 5000 and 10000k
