well im a fan of lots of LR
and lots of LS
for the majority of filtration, and lots of circulation and skimming. when it comes to that, are you planning on having a sump? because that will be a deciding factor in what kind of equipment you are looking at.
i would go with a sand with a very small grain, as that increases area for biological filtratoin, which is very important
as for cycling the tank, i would definitly go with a fishless cycle. check out the article on this website about it. it is far more humane than subjecting damsels to that, and they can be VERY difficult to catch if you want to remove them (they can get to be nasty buggers!)
lighting can be NO
for a FO
tank, but i would get a saltwater spectrum lightbulb, maybe a 50/50 with actinic. this will improve the way your fish look, as saltwater has a complete different spectrum than fresh.
as for strong natured fish, did you have any ideas? agressive or community? tangs are nice, not too agressive as long as there is only one in the tank, and a lot are very hardy. royal grammas, ocellaris clowns, chromis damsels, most gobies, but those are small fish for such a large tank!! what i did when planning the livestock for my tank was picked the one fish i REALLY wanted to have, and absolutly couldnt do without, and then planned my livestock around that.
, good to see ya doin your research
p.s. ask here before you buy anything, it will help keep you from getting ripped off!
