i'm not sure i understand exactly, but what i think he means is he's been lettin' it set in s/w for a bit.
put in the l/r, because ain't no cycling gonna get done without givin' them there benthics something to munch on (i.e. ammonia). you won't develop a colony of ammonia oxidizing bacteria (them's yer benthics) until they have some food (that thar ammonia again). also, please remember that you'll only grow enough bacteria to consume the available "food".
so, once you've put the l/r in the tank, make sure that your cycle has begun by testing first for ammonia, and within a day or three nitrites and nitrates. you won't need to worry about lighting during this period, unless you have l/r that has hermatypic specimens...but then you'd have to consider the fact that most inverts won't tolerate high ammonia/nitrite levels for very long. i just say this because light = $$$ = algal blooms = uck.
also, be sure you've got a quality test kit, mkay? i like seachem (best balance between quality, consistency, and PRICE), but have been spoiled for a little while since we've got an on-site lab.
does this help?
