Wow, it's been years since we had our tank. Like I said, we were part owners in a pet store so we got our stuff wholesale. We would actually go hand pick our stuff for our tank from a place in Atlanta. I guess if we had to start over and pay retail it would cost us around $1500.00. But we still have the tank and stand. DH figures around $1000 to stock the tank. That would be sand, live rock, some inexpensive corals, a few inexpensive fish (fish can be a few dollars to hundreds) and some crabs and snails. Remember, not all fish are compatable with a reef system. Many fish will eat corals and live rock. Lighting is crucial to a reef system. We had a metal halide. Water flow is also very important, some things like more current than others, plus you don't want to create stagnant spots. A larger tank is usually more forgiving than a smaller one. If you have the money, get the biggest you can afford. We used a trickle system for filtration. It was popular years ago but I'm not sure now. We had a problem with hair algae, an indication our phosphates were high. We ended up adding a larger protein skimmer. If your serious about a reef tank, do your homework. If you want a tank with lots of fish, it might not be the best for you. Find somewhere in your area that deals with salt systems. Talk to them and see what they recommend. Once established, other than routine mantenience, they are relatively easy to care for.
