starting up nano; finally..

[bv_reefer]

the reef looks lonely all by itself so i'm ready to start up a nano right beside it (well at least when mik 101 comes and picks up the cichlids, any day now), just had a few questions in terms of equipment though:

for a nano i'm think that crushed coral would be most convenient in terms of maintenance right? sand would constantly clog the filter and be a pain i'm guessing?

for lights should i go with >

it's only a standard 10 gallon, so for filtration should a Hagen Aquaclear 30/50 be sufficient? (it'll be skimmerless)
for flow what would be sufficient? koralia 1 or mj-600?
