Red Sea ReefControl - ATO module

Red Sea ReefControl ATO Module adds a fully‑featured auto top‑off (ATO) to the ReefControl ecosystem without needing a separate ATO controller. Stable water level and salinity are essential for coral health, skimmer consistency and sump stability—so integrating your ATO directly into your reef monitoring platform keeps everything clean, logged and easy to manage.

The module’s digital ATO sensor and 12V DC pump connect directly to ReefControl Lite or ReefControl Pro. The sensor uses solid‑state EC technology with titanium probes and includes a built‑in digital thermometer (accurate to 0.1°C), providing real‑time monitoring, notifications and logs through ReefBeat.

Because it’s part of the ReefSense digital ecosystem, your ATO and temperature data lives alongside your pH, salinity and ORP logs. And when paired with ReefControl Power, you can extend automation into your AC equipment—using temperature and water‑level events as triggers for practical safeguards and quick actions.

The ReefControl ATO Module includes the complete installation kit so you can set it up neatly from day one: sensor holder + magnetic corner bracket (for up to 12mm glass), 3m silicone tubing, splash‑free tube holder (for 4–12mm glass), and a siphon breaker.

If you want an ATO that’s quiet, modern and fully integrated into a reef aquarium controller app, this module is the most streamlined way to add top‑off to a ReefBeat‑managed system.

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.
