180 set up question for water flow

[desertreeflover]

I am researching my needs for water flow and circulation for my new tank. The local distributor of Tunze has me sold on the quality of the product and the flexibility of the system sounds terrific to me.

Here is my tank: 180 gallon custom made glass tank 6'long 24" hi and 24" wide--overflow at one end of the tank against the wall with closed loop drilling on the other end of the tank.

We have purchased Southdown, so a nice silty DSB will be at the bottom 4 inches of the tank.

What would your recommend? This is to be a SPS tank.

Thanks for any and all help!

I saw you liked the Deco Stone concept. My suggestion is to use two 6100 Streams with multicontroller set with tide mode so they alternate off and on- basically they will take turns. I would use the Deco Stone at the top of your rock work, maybe 10" below the surface, it gives a slight upward angle so that should help keep the sand under control.
