I have a 180 Gallon tank with SPS LPS AND Softies. My question is i just bought two 6100s with the multi controller and am trying to get a Wave Box, So i will be having these items plus two penductors on my returns from Iwalki 70. Will this be too much flo. Also i have a two inch sand bed, where can i place these items in the tank without stirring up the sand bed. Also if the wave box is on one side and i put the pumps on each corner side facing the front glass what setting should i use on the controller. And how would i connect the the wave box and the pumps, i was told the wave box comes with a controller.
