All depends. Before you even attemp converting, read, read, read.

Here are questions you should ask your self.....

- Will this be a fish only tank or reef tank?
- Will you be getting into SPS or LPS corals if you go reef?
- Will i wan't a sump??
- Will i want a HOB skimmer or online/in sump skimmer?
- How much flow do i need? (big difference between fish only and reef)
- How much live rock will i need (depends on type)


Im in the process of setting up a 90 reef, with 30 gallon sump. Ive gotten back close to 1500 for my freshwater tank, where i sold, fish, plants, ferts, tank, etc.

Even then, im still dishing out another 700-1000 from my pocket to do the 90 gallon reef. That doesn't even yet include high end lighting, calcium reactors, fish, or corals.

It can be expensive,but it all depends on what you are gona do. Read, read, read.

By the way, im saying that amount going used.

Well like the other member said I am also kinda new at this been in it for a few months now and I did what you are thinking about doing I converted from a fresh water 55gal to a 55gal sw tank and all in all I have spent probably over $500. but before you worry about going out and getting anything to start two points of advice that I got when I decided this is what I wanted to do 1. Read and Research anything and everything you can get your hands on. get all the info you can before you make any choice because you cant make a choice if you dont know what is involved. and 2. start slow a famous Quote in this hobby is "ony bad things come in a short amount of time"

but to give you a idea of what I had to do was
1. new filter (depends on the kind you are using now)
2. make sure you have plenty of salt on hand to start with I have had really good luck with "Instant Ocean" but thats just preferance.
3.Decide on the type of tank(mine is a fish Only)
(if you plan on doing a just fish with out any hard to keep corals then your normal tank light with work but if you want the reef or harder to keep corals then your going to need to upgrade you lighting to a higher output)
4.protein skimmer (if chosing a fish only one then you really dont need one unless you plan on having alot of fish)
5. choose your substrate (I have heard sand is better but I used crushed coral again I think it all comes down to preferance)
6. kits are one of the most important thing you are going to invest in because you need to keep a constant eye on your levels salt water fish are alot more sensitive to change than fresh water.
7.a hydrometer to test your salt gravity of your water.

Thats all I can think of off the top of my head and thats just for a basic setup. some people in this hobby have whole basements set up and devoted to this hobby but I wish you the best of luck and make sure you keep an eye on the threads on here because I have found a countless # of threads that have helped me out. Good luck and welcome to the marine world. :thm:
