which watermelon? my pink alien eye and bazooka joe are on th bottom about 26" from a 400 watt 20k radium in a lumenarc mini, the jaydas is about 19" below the same radium, the tubbs and the golden eye are about 14" below(these two i am trying to move around and see if i can get the colorations that i see on reeffarmers.... i have yet to get the red watermelon, or the eme, or mummy eye, but it will try to get them soon.... the bazooka, AEW, and Jaydas are all very happy and beautiful in color.... moderate flow, not tooo low as i noticed they didnt like low flow... just my opinion..
