lights please help

There used to be an old thumb rule of 3 watts per gallon. There is now alot more stuff that goes into lighting nowdays but for a 22 inch tall tank I would think that rule would be good. If your just gonna do softies and LPS the PCs could do but thats it. 110w of T5 would be ideal though and should give you plenty of light for that tank.
 
I think they're 12" wide so they would fit as long as nothing is hanging on the back (overflow or hob skimmer
