fish tank supplies
 

Im a beginner in fish tanks and i wanted to know when you buy a fish tank what supplies do you need for the fish and the tank?

can you please list the items.

That all depends on what sort of tank you're setting up. This is the saltwater section, so your saltwater options include FO (fish only), FOWLR (fish only with live rock) and reef setups. I don't know much about marine FO setups, but I do know that you'll need more specialized equipment if you're planning on keeping corals in a reef setup.

what supplies exactly would you need for a 120 gallon tank reef setup?

is it the hardest set up out of all of them to care for?

You would need a lot of money. Just the live rock alone at a minimum of 120 lbs would cost $600-$1000 or so. If you want to do corals you'll spend a lot of money on lighting as well. Then there's the protein skimmer, sump, salt, etc.

If you don't have a couple thousand dollars to invest in the tank you'd be much better off doing a freshwater tank. 120 gallon freshwater gives you a lot of options.

I think your best choice is to start out with a FOWLR setup.
Things you'll need:
powerheads (1000 gph system)
100 lbs of base rock
10-20 lbs of live rock
50-100 lbs of substrate, depending on how much you want to spend
fluorescent strip light/cover
filter (optional, any kind will work)
heater (300-400 watts)
thermometer
hydrometer/refractometer, depending on how much you are wanting to spend
master test kit
salt mix

A 120g FOWLR setup will probably cost you $1,389 + the cost of the tank and stand. If you don't already have the tank/stand, I would reccomend setting up a 55g FOWLR system if you don't think you have the money for a 120g system.

OK, so I went a bit overboard. But eventually, you will end up needing nearly everything I've listed, plus a good many things I haven't thought of.

hope that helps
