What do I need to transform my Eclipse6 to a saltwater tank?

[koop]

Right now my tank is freshwater, and i would like to buy stronger lights to support anenomes. What else can i put in a small tank like that?

for anemone you would be talking a Metal Halide pendant ( or possibly Something T5). And you would want a skimmer, and a powerhead. You would want aboutm 10 lbs of Live Rock, and enough live sand for a 1-2" sand bed. You would be able to keep one small fish, and as many corals as you can fit (so they arnt touching). With the anemone in there I might think a clown would be a good fish. With such a small tank be prepared to add top-up water every day, and keep a VERY close eye on the water parameters.
