I don’t know why I can’t edit this however; the tank is my 70 shallow that is set up now on a reboot. See build thread. This was pre-hurricane Ivan, 95% homemade rock, Garff recipe, with Garff grunge as the biological kick off. Ran a 250 wtt 16 K metal halide on a track rail running back and forth over the tank. Supplemented with a VHO Actinic fluorescent bulbs. Tank was doing fantastic until the hurricane.
