What do you mean by best types of reefs? There are many kinds (e.g. deepwater, SPS, LPS, Softies, Coldwater, etc...)
As a start, make sure you have at least 10x system turnover per hour on your main pump (after calculating head pressure). Then invest in a good light fixture from a reputable brand. Personally I'd stay away from anything made by Deep Blue. Then once you're cycled and stuff you can look into upping your flow, adding a skimmer or UV, etc...
And I'd recommend buying aragonite-based substrate.
