Recently tore down my RSR XL 750. Blowout sale of all components. Great opportunity to get high end stuff for your reef tank at half the retail cost. Everything must go. Reef octo skimmer, Ecco tech LEDs, pumps, powerheads, apex controller with tons of accessories, Alger scrubber, T5 light fixture, par meter, top off tank, and much more. too many other extras to list. If your looking for anything reach out to me first for a solid deal.
