which one for me?

have a 72 gallon aga bowfront and want a tunze for my reef but don't know which is best for the tank. like the idea of being able to control it , which size? and which contoller?

[rvitko]

This depends on type of corals. 7300/2, 7400/2 and 6000 Stream are all possibilities and all can be controlled with a single controller but it will depend on whether you do SPS or LPS or softies primarily. For a basic polyps and softy tank I would get the 7300/2 for a mixed tank with lots of LPS I would do the 7400/2 for an SPS intensive tank the 6000.
