The Red Sea ReefControl ATO Module is an essential add-on kit designed to seamlessly integrate a complete, fail-safe Automatic Top-Off (ATO) system directly into your existing ReefControl Lite or ReefControl Pro controller.

It allows your main controller to manage water level stability and monitoring, eliminating the need for a separate, dedicated ATO controller.

Components of the Module

The module contains all the necessary hardware for a complete ATO system:

  1. ReefSense Digital ATO Sensor:
    • Solid-State Technology: Uses slim-line, multi-input titanium probes and Electrical Conductivity (EC) technology to sense the water level. This design has no moving parts (unlike traditional float switches) that can fail, clog, or get stuck, ensuring ultra-reliable operation.
    • Built-in Digital Thermometer: Includes an integrated, highly accurate digital temperature sensor (accurate to 0.1 C). This gives you a real-time, logged temperature reading from your sump or ATO chamber.
    • Fail-Safe: Features built-in safety shutoff and backup probes to prevent overfilling.
  2. ATO Pump:
    • Quiet & Variable Flow: A compact (1.8" diameter), 12V DC pump that is quiet and energy-efficient (6–10W).
    • High Performance: Max flow of 300 LPH/75 GPH and max head of 2.5m/8ft.
    • Serviceable Design: The pump's impeller chamber is designed for easy disassembly and cleaning.
  3. Complete Installation Kit:
    • Sensor Holder: Includes a magnetic corner mounting bracket suitable for up to 1/2” glass.
    • Tubing: 10-foot silicone tubing.
    • Safety Features: Includes a siphon breaker to prevent accidental reverse siphoning and a tube holder for silent, splash-free flow into the sump.

Ecosystem Integration and Automation

By plugging the ATO Module directly into an available port on your ReefControl Lite or Pro, you gain the full benefits of the ReefBeat App:

  • Salinity Stability: Provides an automated, secure method to replenish evaporated water, which is the most effective way to maintain rock-solid salinity—the single most critical parameter for coral health.
  • 24/7 Monitoring: Tracks and logs the number of top-offs, the volume of water added, and the water level status.
  • Temperature Automation: The built-in temperature sensor provides a dedicated temperature reading for your sump, which can be used to trigger automation rules via the ReefControl Power unit (e.g., turn a chiller or fan ON/OFF).
  • Critical Alerts: Receive notifications if the ATO runs excessively long (indicating a possible leak or pump failure) or if the RO reservoir runs dry.
The ReefControl ATO Module is the smart, reliable solution for adding fully integrated water level and temperature control to your Red Sea system.

LIGHT

LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.

MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height. 

HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.

FLOW

LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.

MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.

HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.

SKILL

ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.

While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
