Hey emily
Glad to see that you are ready for a tank ,not many 14yr olds would think of starting a reeftank ,kudus
I want to give you list of things that you would need for your tank ,this will give you an idea on what you are going to spend.I would like to see you with a successful tank and knowing what you will need is half the battle
tank--for the 65 gal --add the cost of the tank
live rock --about 1lbs per gal of tank water ;IE 65 gal tank 65=lbs ,you can probably get way with 50lbs .---around $175 a box
lighiting --if youre doing reef ,t5s will do for beginners -good one around $250 (complete fixture with bulbs)
return pump --mag drive 7 or 9 will do around $60
skimmer -----i would say a good one runs around $250 and up
RO/DI unit (filters out your tap water to make it good for your reef)
sand ----say $30 to $40
heater
sump
and chiller --you may get away with fans if your place doesnt get to hot in the summer or you have the AC on all the time ---a chiller NEW is around $300 and up
I not trying to push you out of the hobby ,i just want you to get the feel of what you could or will be spending ,Note this doesnt include live stock (fish ,coral ,inverts and other stuff you might need)
the hobby does get pricey ,but worth every penny
