Some great suggestions reefgeek.
My tank is actually 72 long 30 wide and 24 high so I think the 250's are ok.
I actually do have Ozone already, just forgot to mention it

I have a Red Sea Aquazone Deluxe Ozonizer (w/ ORP Controller & Probe) - 200 mg/hr
I have heard so many conflicting things about UV. What do you think it adds to the tank that Ozone does not?
I am using a Tunze 3155 Ozmolator for my top up system. How does auto Ro/DI work?
Underneath my tank will be totally empty and I love the idea of a Frag Growout tank. I will got on that immediatly.
As for the Calcium reactor, I am considering it but unless I go with a lot of SPS do I really need it?
My tunze equipment just arrived. this is getting exciting now!
Thanks!
