when you add on the end capps its come out to be 70 " with a clearance of 1 ' per side
it's like when you buy 2x4's they are not 4"wide they are 3.5 " then you add on the dry wall and presto you have the 2x4 studd ranging at 4" with the .5" added on
dont worry the 68" will be great any ways they will reach the extra 2" on each side not to worry i ran 4x48" vho bulbs on my 280 and light the tank.
SO its noy going to be a problem...

you dont want it a snug fit at the end s of the canopy if you have to take them out for some reason, you will like the extra clearance..
