okay i just bought a 55 gallon tank with hood and lights
I bought some white live sand....
and some instant ocean
i also purchase a "skilter filter" its like a protein skimmer and filter in 1

live rock, not a MUST, but a HUGE plus... but i would highly recomend getting 25-70 lbs of lr...

Dragonfish has given some sound advice. Live rock and as much as you can afford.
Normally i would recomend a minimum of 1kg of liverock per 2 gallon volume tank but a 1:1 ratio is even better
