I agree with reef and wasp, you should have at least 2 - 4 thou ready to burn before you start a successful marine. I just added up all my spending in the last 12 months and it came to $ 3100.00 this is for a basic 200 lt four foot tank, no sump. I get great colours with sps and good lps growth but still consider my tank very basic. AND that $ total doesnt include live rock, corals or fish !!! just gear
If you cant afford the gear at once just buy it slowly and build it up till you have it all. Then set it up
Test kits alone set you back a mint at first
