I started less then a year ago my 28 gal reef tank, I have 6 corals, most of them are very hardy and easy to keep,
I have 1 fire shrimp, whole bunch of crabs and diff snails + I got a pair of clowns.
I have some pic a did a while ago
Reef is defenetely harder and more expensive to keep, but its really great to have it.
Mucho is right it will be very easy to upgrade to it later, just make sure u do not use
much medication in your main tank.
U would defenetely want LR, dont be cheap on this one its a main beauty of the tank. Buy uncured rocks its very easy to cure them.
I spend on mine $200.
Most expensive things:
Lights: $150 and up for your tank, I have this ones
http/www.jlaquatics.com/phpstore/store_p...t_ID=pc-ll24652
they are good for fish and many corals too. Of course for some corals u would need MH lights they start from 450 for your tank.
But they need just for some corals which are mostly very hard to keep. So go with compact lights. Make sure it has Actinic light and Moon Led, its really cool u will never regret it. Buy the ones with the legs mounted.
Skimmer: it is not important if u do often water change, but I would not risk to go without it, I think 120-180 bucks u spent for it will
cover your expenses in case of the ammonia spike or other dirty stuff.
External Filter: u can get one up to $100, dont buy hang on, it too noisy. Filter will let u to put media to remove phosphate and other stuff from the water. I would not go without one.
Everything else is a change
), for sure u would need lots of other stuff but they are not that expensive.
Let me know if you need more help.
P.S. I forgot, u would need good RO/DI unit, trust me u dont want to buy water from LFS. A good one will cost u apx $150-200.
