SB Reeflights 18" Sbox Basic setup. It's about 1.5 years old, used approximately 4 months @ 8 hours a day, 20-30% output. I tapped and drilled the tank mount rod hardware with an extra hole so that it will also fit securely onto a 20 Long, it still fits the smaller tank sizes as well, the only difference is the addition of the screw hole for 20L. I have moved to a smaller Coral QT setup. Comes with the tank mount hardware shown below. Hanging mounts not included. I'd prefer local sale, but I will ship.
