[APD] Re: anyone running T5's?6

I totally agree with what Richard wrote - new bulbs do make a huge difference.  
However, the bulbs I replaced were less than a month old - there was a 5W 
difference between each bulb.  Over a 30gal tank, that's a 33% increase in

Don't underestimate the point that they're new bulbs which always
work better than the ones you replace. Light decay is sharp at the beginning
then drops off to a slower rate of decay; but when you first turn them
on they're brighter than they'll ever be again.
