I have about 7 different acros/millis each about 1-2 inch frags. They are all sitting on my frag rack right now. they have been in the tank for about one month. Minimal polyp extension, but are encrusting the plug. What is a good rule of thumb to use for moving them from the rack and then placing them on the rock? I will be using marine epoxy as well as super glue to attach them to my rock. 90g bowfront tank with 42 leds: 21 3w royal blues, and 21 3w neutral whites. I would say that my flow is on the low end with 2 hydor 2's as well as my return pump which is a quiet1 4000.
