Description
REEFER 425 G3 Deluxe – White (incl. 2 X RL115 & arms) Red Sea Aquarium
The REEFER 425 G3 Deluxe is a large-format reef aquarium system designed as a near “turnkey” foundation for serious reefkeeping. The “G3” generation features upgraded plumbing, stronger structural build, integrated automation (ATO) and sump infrastructure. The “Deluxe” version indicates a bundle including the display tank + cabinet/stand + sump + pre-plumbed plumbing + included lighting (2 × ReefLED RL115) and mounting arms. Essentially, it gives you the structural core of a premium system — you supply return pumps, wave makers, skimmer, live rock, livestock, etc.
REEFER 425 G3 Deluxe - White (incl. 2 X RL115 & arms) Red Sea Aquarium
When you purchase the 425 G3 Deluxe (White + 2 × RL115 & arms), you should receive:
The display aquarium (425 G3) with ultra-clear glass, euro-braced construction.
The marine-spec cabinet/stand (White finish), built to support the system (including leveling feet, designed for marine environment).
The in-cabinet glass sump and pre-installed plumbing (mechanical filtration compartment, media cups, drain & return plumbing pre‐integrated).
2 × RL115 LED fixtures inclusive, with mounting arms/pendant kit (as specified).
The ReefATO+ auto top-off & monitoring system (sensor, leak detection, temperature monitoring).
Warranty provisions: G3 systems include a standard 3-year warranty, extendable to 5 years upon registration (varies by region).
Construction of REEFER 425 G3 Deluxe
Euro-brace and thicker glass: The 425 model (and above) uses euro-braced glass (a reinforcement bar across the top) for additional structural strength — valuable for larger volumes.
Hydrodynamic plumbing: The G3 upgrade emphasises quieter, more efficient flow — fewer sharp turns, larger piping, precision gate valve to control downflow quietly.
ReefMat-ready sump filtration: The sump design is REEF-SPEC, with dedicated compartments for mechanical filtration (e.g., fleece roller), skimmer, media, and hardware.
Integrated smart monitoring: The built-in ATO sensor monitors water level, salinity, and temperature; leak detection helps protect your investment.
Premium visual aesthetic: Ultra-clear glass, beveled edges, minimal visible framing, clean overflow box, hidden plumbing (when set up properly) result in a high-end appearance and display.
Reinforced cabinet/stand: Built from marine-spec plywood (laminated panels, epoxy doors, stainless hinges) to survive the marine environment and support the tank for years.

This system is ideal for hobbyists or enthusiasts who:
Are ready to step up beyond mid-sized tanks and want a serious foundation for a thriving reef ecosystem — 343 L display volume gives significant room.
Want a high-quality, pre-plumbed system that reduces major build effort — rather than constructing everything from scratch.
Plan to stock a mixed or advanced reef environment (LPS, many SPS, moderate fish load) and want a robust structure (strong cabinet, euro-bracing, large sump) to support long-term stability.
Have the physical space and are ready for the floor/structural support, delivery logistics, and maintenance required for a system of this size.
Value integrated smart features, and are willing to invest both in the initial purchase and in the supporting equipment (pumps, skimmer, live rock, etc.).

Installation
Space & Weight: With ~433 litres total water volume plus substrate, live rock, and equipment, the system will weigh several hundred kilograms when filled. Ensure your floor and stand location are level, structurally sound, and can support the weight.
Footprint & Access: With dimensions ~120 cm × 60 cm (tank footprint) + cabinet + access space around it, you need sufficient room for service (behind, sides) and for the stand depth.
Delivery & Installation Logistics: Large systems often ship in crates; you’ll need to plan for handling, placement, leveling, plumbing connections, and initial setup.
Lighting & Stocking Plan: The included 2× RL115 LEDs will provide good coral-safe spectrum and coverage, but depending on your rockwork height, coral type, and desired growth you might evaluate whether extra lighting (or higher output fixtures) may be beneficial.
Circulation & Equipment: Although plumbing is integrated, you still must choose appropriate return pumps, powerheads/wave makers, skimmer, etc. Good circulation and filtration are key to reef success.
Maintenance & Monitoring: With large water volume you have more buffer, but you still must monitor parameters (alkalinity, calcium, magnesium, nitrates, phosphates), perform water changes, service equipment.
Budget for Extras: Don’t forget to budget for live rock, substrate, corals/fish, test kits, salt, dosing, and power costs — a tank of this size has higher operational expense.
Startup Phase: Allow time for cycling, live rock maturation, and parameter stabilization before heavy coral loading to avoid early issues.

Pros:
Excellent build quality for the size: Integrated sump/plumbing + strong structural tank + premium lighting bundle.
Large display volume allows more ambition in aquascape, coral stocking and fish load — greater flexibility.
Included smart features (ATO, monitoring) reduce some complexity of setup and enhance stability.
Euro-braced design provides peace of mind for long-term durability.
