hanging my freshwater to saltwater HELP

[Steve_the_nucks_fan]

Thanks for the insight. I don't know if I should try and sell my current tank and everything I have for it and start fresh or keep the tank and swap it to saltwater. I like the size. My tank was setup has saltwater with the previous owner. And would assume the lights will work.
I would like to get the cycles going to get the water where it needs to be for adding wish so if you have any addvice on this please let me know. And if you know any where I can get supplies for cheap that would help also. Thanks for the feed back everyone.
