Need advise

[James983]

I am currently in the process of setting up a 150 gal. 72x18x25. It will be a reef with some sps, mostly lps. I want a DSB approx. 5-6". I keep changing my mind on how best to get water movement.
The tank has 2 overflows and I will be using a 30 gal. as a sump/refug. I'm unsure if I should buy the Wavebox and 1 6100, or 2 6100s with the multi controller. Both are expensive options, but I want to get it right the first time for a change. Any advise is greatly appreciated.

Doh!!.............meant advice.

I would go wavebox and 1 6100, the wavebox does not disturb the sand and the flow is more LPS friendly. I would put the 6100 on the opposite side and place and SPS nearer the 6100.

That was my preference, thanks.

I'm very happy with the combination of wavebox and 6100. I actually have two 6100s. You'll want one 6100 on the opposite side from the wavebox if you have a fine sand bed. I had both 6100s and the wavebox all on the same side (6100s aimed at opposite long edges of the tank) and they created a huge mound of sand below them, drawing it along the entire length of the tank. This happened even on interval 2.

I'm not running interval 2 with the 6100s on opposite sides though. I suspect the mounding problem would still occur when the 6100 on the same side as the wavebox runs at maximum.
