Wasn't sure if 6 Watts per gallon would be overkill if I added a second 96

I've got bulbs almost 3 years old and they're still going strong.
Six watts/ gallon might be overkill depending on who you talk too : ) With that
much lighting it would really be hard to keep up with a proper dosing routine
and also leave little room for error.
