Welcome to TR, Paul. Research, research, research then, before purchasing anything throw out a question to us. This an expensive hobby. Making uninformed decisions is a big mistake. No one on this forum, not even the vendor members, have hidden agendas. Here are a few member tank threads that will give you some ideas to ponder.

There are many more. I picked these to give you some idea of what we have gone through to achieve our reefs. You will get many ideas and find there is not one way to do things, but many different ways, to be successful.
Looking forward to helping you.
