More streams or wavebox

[Snaphook]

I currently have a 210g 72 x 24 x29 primarliy SPS and have 2 6100's and a 7095. My question is what would it be better to get another 6100 or 2 or get a wavebox. Here are my concerns about the wavebox: Will make a slooshing noise as my Overflows are off center and tank failure. Any comments are welcome.

Your concerns are valid but tank failure is not likely in the immediate future unless the tank is already old, unlevel or poorly made. It will though reduce tank life. The wavebox adds a nice flow effect that tends to help remove detritus from the rock structure and enhance polyp extension. It is what I would choose.

As far as level goes. My tank is off about an 1/8" front to back, is that too much for the wave box?

If it is a straight front to back off level and not a torque it is not a big problem but if it is torqued it could be a big problem, (one corner is lower than the diagonal corner)
