Christmas is quickly approaching and I am thinking about getting another tank. I have decided to try something different and a little more challenging than my 20 gallon freshwater tank. The only thing that still has me debating about trying this challenge is the cost of saltwater setups. If I were to do this then I would get a 40 gallon breeder tank. 36"x18"x16". I am trying to find a cheap light that will fit this tank and be ok over an open top. I plan to make this a reef tank so the light would have to be capable of supporting corals. I would also get a sump right away to save money down the road. What equipment would I need and where can I get it cheap? I am just trying to get an idea of the cost vs a 75 gallon freshwater setup. Thanks for all the help guys and I hope to be able to afford this setup.
