I'm using a blueline 40HD-X as my return and 2 Tunze 6060s for circulation in my 180. I'm only wanting the 3-5 times turn over display to sump so the skimmer can do its job. Just a thought. Also, keeps micro bubbles/water noise down. BTW the tank is not up and running yet! but the equipment is on its way! Lots of research and testing with current tank.
