Where are you guys placing them in the tank? Mine is placed half way in the tank right under a 250 in med flow. It's not doing much, just sitting there. I don't know if I should increase flow, lower or higher light?
Chris I have mine close to the top off my tank about 8" below the surface and pretty close to the center of the tank. With moderate flow, I get great polyp extension and growth. 2X250wt 14k lumenarc bulbs.
Sometime depending on the condition of your tank, undata will not grow much ... I would check the parameter to make sure ... but they do like more lights so 2/3 of the way up and medium flow will be good.
The polyp extension is good but the color is not deep. It just hasn't really done anything so I was thinking about moving it and didn't know whether to put it up or down. Maybe I'll get a new photobucket account so I can post a pic.
