Help with placement.

[RcToners]

Okay so I have a 150 gal, I purchased two tunze 6105's with the 7106 controler. I am having a very hard time trying to figure out where to place the pumps. It seems no matter where I put them they are blowing up sand or sucking air bubbles from the top. Here is a full tank shot, any ideas where I should try to place the pumps and maybe what type of settings for the controller. At this point I will try anything. I have put them in the back corners facing each other, Ive tried facing them in a diagonal pattern twords the front glass. I want to keep them hidden as much as possible but any help would be greatly appreciated.

To avoid bubbles you need to move them lower in the tank, they should be at least 6" from the top. To avoid stirring up the sand you should step down the power, try using the 12V jumper that was included with the power supplies. You can increase the power later when the corals have grown in and things are more established, I think your placement was fine, back corners aimed to the front almost diagonally across the tank.

They came in the white boxes the power supplies were in. As boboxx said they are in little baggies.

The most recent power supplies include 12V and 18V, 18V is preinstalled. The oldest ones included 15V and 24V. They come in what I refer to as crack baggies because they look like the kind of baggies you see being pulled out of someones pocket on Cops. Like a 2" by 2" ziplock bag, they were in the white box that the power supply came in that was inside the box of the 6105 pump.
