Red Sea ReefSense – Magnetic 4-probe holder

Red Sea ReefSense Magnetic 4‑Probe Holder keeps your probes organised, correctly positioned and easy to service—helping you get more stable readings and a cleaner sump layout.

Designed for the ReefSense digital probe ecosystem, this holder securely positions up to four probes/sensors so they’re not bouncing around in high‑flow chambers. That makes calibration, cleaning, and day‑to‑day maintenance faster, and reduces the chance of cables pulling on probe bodies.

The magnetic mount is designed for aquarium glass up to 12mm thickness, making it suitable for many modern reef tanks and sump designs. It’s a small accessory that makes a big difference to overall “cabinet quality.”

If you’re running multiple ReefSense probes (pH, salinity, ORP, temperature), this holder is the easiest way to keep your system neat and your readings consistent.

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.
