I have purchased a 120 gal for a mixed reef. I am currently planing for the water movement. I am torn between a CL with a pump and OM 4 way or Tunze streams and controller. I bought a steam pump that was not vairiable and I know how much water they can move. I dont like the Idea of drilling all the holes in my tank and all the plumbing. Can someone suggest a Tunze product for me that would help me make a decision.
