I've got to ask....whats the pricing difference between Warm and cold tanks?
fish, lights, corals etc....I work in a Seafood restarant and we had a lobster tank. It seemed that they really didn't do too much execpt keep it cold. They checked the salt once in a while.

In general....cold tanks are similar in costs to a fish only warm water set up.....but cheaper than an sps system. Some particulars to cold water setups are...
1) They need only enough light for the viewer since most critters are non-photosynthetic.....unless you want to grow kelp or seagrasses....then a bank of T5's will be needed.
2) maintenance is less.....with less algae
3) fish disease is near non existant
4) No reactors or Ca additions are necessary....minimal alk additions are needed.
5) Flow requirements are the same as a fish only system....but, far less than an sps system.
6) you do need a chiller....which is the only real cost addition over a warm system.
7) stock is hard to get unless you live near a coast....but, more and more cold water fish, anemones, snails, etc are coming through the warm water trade.
8) the tank MUST be acrylic to prevent sweating....and thicker than 1/2" to avoid the sweating issue.
9) the fish need to be fed less than a warm water tank....but, the inverts need to be fed ALOT more since most are non-photosynthetic
10) pretty much all you need is a tank, sump, skimmer, chiller, and a return pump.
