REEFER S-850 G3 Deluxe - White (incl. 3 X RL170 & arms)
The REEFER S-850 G3 Deluxe is built for experienced reef keepers and professionals who:
Want one of the largest plug-and-play reef systems available.
Plan to maintain complex SPS/LPS coral systems or large fish populations.
Need a silent, stable, and visually stunning display for home or office.
Prefer an all-in-one integrated system with proven Red Sea engineering.

Installation
Space & Support: This is a large and heavy system (~1000 L total). Ensure solid structural support and a perfectly level installation surface.
Lighting & Coral Plans: The included 3 × RL170s are optimal for full coral coverage. SPS-heavy aquascapes may benefit from strategic placement or an additional fixture for maximum PAR balance.

Equipment Add-Ons: You will need a protein skimmer, heaters, powerheads/wavemakers, and an RO/DI unit.
Maintenance Access: The cabinet provides wide access doors and removable panels for effortless sump maintenance.
Electrical Safety: Use a dedicated circuit with GFCI protection; route cords through the rear management panel.

Pros:
Largest volume and footprint in the REEFER S-Series lineup.

Fully pre-plumbed and ReefMat-compatible sump.
Included 3 × RL170 lights ensure exceptional PAR and color spectrum.
