The first money you should spend is on a copy of "The Concientious Marine Aquarist" by Robert Fenner. That book will help you more than any other purchase you can make starting out. You can certainly have a successful marine tank on a budget as long as you set it up right to start with. Patience is the key. You can, for example, buy mostly base rock instead of dropping a couple of hundred on all LR
. It will just take longer to mature into something that looks nice. Along with patience, as jamal-188 mentioned, is research. Read and read and read some more before you act. We will help you in any way we can. If you are handy with tools, you can build quite a bit of the equipment you'll need instead of buying it. Welcome to AA.com!
