You will have to scrap the filter material and scrub the tank down *don't use soap/widnex!* 8O
I would start with LS
and as much LR
as possible. FOWLR
setups can use the same lighting... but I might change the bulbs to actinics/50-50's so that things look nice. Reef lighting will be more expensive... what setup do you want? You can use the Whispers with new media, but most (including me) would talk bad about HOB
filters with filter media. They can trap deterius and if not cleaned very often, and can lead to nitrate production. If you get 1.5-2 lbs of LR
, that's all the filtration you'd need.
Get some powerheads to reach 10 X water circulation (would just go with 2 MJ1200's). Other than that... save up for a good skimmer and you're good to go! LOL
... basically you can use your tank & hood. Most of the other stuff will have to be replaced/cleaned. Good luck!!
