Step 4: Start Buying What You Need
Once you have made your decisions and come up with a final list of all the items you'll need to set up your new aquarium, start shopping. However, keep in mind that the saltwater aquarium hobby is supposed to be enjoyable. If you cannot afford to do so, don't overtax your wallet and stress yourself out by trying to buy everything all at once. It may take a little longer to put things together, but it's easy to plan out a simple budget, allowing a certain amount of funds to be spent each payday until you have what you need.
