Red Sea REEF-FRAME 350 Aquarium System

The Red Sea REEF-FRAME 350 is a 353 L reef-ready system built for reefkeepers who want more display space and flow flexibility while retaining complete control over their equipment choices. Its 120 cm display, eurobraced ultra-clear glass, reinforced cabinet and 71 L sump make it a strong platform for a serious mixed reef or SPS-focused build.

REEF-FRAME is engineered around structural support, quiet operation and flexible water movement. The aquarium sits on a marine-spec plywood cabinet designed to support the full glass contour, while the central overflow and ReefGate high-precision valve provide simple, accurate downflow adjustment. The 350 adds dual 25 mm return outlets, allowing either single- or dual-return-pump configurations.

Why Buy from EasternMarine Aquariums?

EasternMarine Aquariums is New Zealand's premier saltwater aquarium importer. Our team can help you select the right system, pair equipment correctly, and plan livestock so you can build a successful reef from day one.

We take livestock seriously. That's why we don't sell anything we wouldn't be comfortable putting in our own tank.

As we are direct from source, we import and sell direct to the public. This means you can buy with confidence knowing EMA prides itself on excellent handling and conditioning protocols.

Fish

All our fish held in a quarantine system for a minimum of 3 weeks. During this time, regular water changes are performed, and twice daily (or sometimes more) feedings are performed.

Copper is dosed and checked twice a day for ich and velvet.

During this treatment fish are given formalin baths for brooklynella and a minimum of 3 praziquantel doses is performed for flukes.

Coral

Our coral is quarantined for a minimum of 3 weeks, just like fish. During this time, regular water changes are performed, water testing done, and once a month a Fauna Marin ICP Total is performed.

Corals are inspected for pests/general health and are provided with a pest dip once a week for at least 3 weeks.

If we see signs of pests, the quarantine period is extended and/or additional dips are performed

If coral is bleached/unhealthy, it will remain in quarantine until healthy enough to sell.
