Wow, this is my dream tank setup, any quotes on who can make a tank with these dimensions. Anyway, I've quietly been researching equipment for this dream tank.
Skimmer: SWC xtreme 300 ( bioload rating:heavy bl,365 gallons, med bl 475 gallons, light bioload 690 gallons for right under 500 dollars)
Lights: probably an ATI 8 bulb t5 fixture, no halides because do not wish to run chiller, led's too expensive and too risky in my opinion, saw a 300 g reef with 3 ecoxotic 100w cannons and tank was breathtaking, resembled the ocean like no other, unfortunately, wife prefers full tank lighting on our current t5 120 gallon
I would do two mp60's Simply because Ill be worried about three holes being drilled in my tank for drain and returns, would not be able to sleep at night knowing tank has been drilled all over for oceans motion closed loop.
Side not, it looks more and more that I will be settling for an aqueon 210 gallon as my next display.
Aqueon 210gallon 72x24x29---$640
Custom 280 gallon 72x36x25--$2170
Custom 300 gallon 72x30x30--$2780
