Red Sea ReefControl - ReefSense Port Expander

Red Sea ReefControl ReefSense 4‑Port Expander is the upgrade that turns ReefControl Pro into a full multi‑sensor reef monitoring platform. If you’re adding salinity, ORP, ATO, leak detection and temperature on top of pH, the expander gives you the extra ReefSense ports to scale cleanly.

The expander plugs into the ReefControl ecosystem and allows you to run up to 7 ReefSense digital probes and sensors on a single controller setup—ideal for larger reef aquariums, high‑value coral systems, or anyone who wants more safeguards and more data logging through ReefBeat.

Because ReefSense uses a common digital interface, you can connect any compatible probe/sensor to any available port—no port‑type limitations and no complicated programming. Add more sensors now, or leave ports free for future upgrades as Red Sea expands the ReefSense range.

If you chose ReefControl Pro for its expandability, the 4‑Port Expander is the accessory that unlocks the “full ecosystem” experience.

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.
