Hi, I am setting up a mixed reef, LPS dominant tank. Tank is 45X27X20. For those with MP40's what mode / intensity are you running? I currently have mine in lagoon/ref crest random @ 30%. Tank just finished cycling and I moved a couple of Blasto frags from my other tank and they are not opening completly. I put them on the sand bed. I aslo have AI leds but I have them max @ 20/30/35 so I don;t think it is the lights?? Below is how the vortechs are setup they are about 5 inches from the waterline adn about 13 inches from the bottom of the sand, centered.
