looking for guidelines to set up a 70 gal tank, equipment.

This an answer I left for someone else who asked a similar question. Also go to www.reefcentral.com The membership is free and people are great about answering questions.

A good place to start is your local fish store (LFS). You will pay a higher proce than if you buy your setup online, but shopping lcoal has two advantages: you can see what you are buying, and you then have someone you can talk to if you have a problem. As a former fish guy, I hated it when someone would start a question with "I bought this online and I was hoping you could help me with it." That being said, get all your dry goods (food, medication, etc.) online or wherever you can get it cheap. No point in paying higher prioces for something like that.

Get your fish local because you can look at them. If the store quarantines their fish before they sell them than buy from that store. I also recommend having at least a ten gallon tank that you can set up in a hurry as both a quarantine tank and a hospital tank so you can reduce the medications you are using and use a wider variety of medications (copper sulfate is great for ich, but it will kill all your corals) as well as not having to treat fish that dont need treatment.

As far as supplies, here is a basic list for any setup that I would put together for a customer:

I am assuming that you are going to get a large tank (in excess of 60 gallons)
