Red Sea 3-in-1 ReefATO + ATO System

The ReefATO + ATO System integrates an auto top-off function, water level sensing, and a temperature probe into a single package. Its fail-proof, solid-state EC water level sensor minimizes false alarms, while back-up pump-OFF probes are positioned just above the normal pump-OFF point to prevent overflows. Real-time readings are available through the ReefBeat App, so hobbyists can monitor water level and pump status from a smartphone. The embedded temperature sensor is pre-calibrated to ±0.1° accuracy, aiding in rapid detection of temperature swings that can stress corals and fish. This system reduces maintenance by maintaining stable salinity and water level, essential for consistent reef health. The app connectivity supports remote monitoring and quick adjustments to dosing or topping-off routines when needed.
Red Sea Reef Energy Plus 500ml (AB+) All in One Coral Food

Reef Energy Plus is a comprehensive all-in-one coral food designed to support soft corals, LPS, SPS, and non-photosynthetic corals. The formula emphasizes growth, color, and resilience, with laboratory-backed data showing faster growth compared to previous two-part formulas. Its automatic dosing capability makes maintenance easier, enabling regular feeding without manual administration. The product is designed to remain stable even when used with automatic dosers and can be kept unrefrigerated and unstirred for a week, simplifying dosing schedules. Users should adhere to dosing guidelines to prevent overfeeding and ensure balanced nutrient levels in the display tank.
Red Sea Coral Pro Reef Salt Mix Small Bucket

Coral Pro Reef Salt Mix is formulated to promote accelerated, healthy growth and enhanced vitality across corals. Its composition supports the uptake of major, minor, and trace elements required for skeletal development. The salt mix emphasizes the critical calcium, magnesium, and carbonate balance that corals rely on to build skeletons and maintain stable coloration. This small-bucket option is ideal for hobbyists managing smaller systems or those who prefer incremental, controllable salt dozes during water changes. Regular testing remains important to maintain precise salinity and alkalinity levels for optimal coral health.
Red Sea Coral Pro Reef Salt Mix Large Bucket

The Large Bucket version delivers the same Coral Pro Reef Salt mix in greater volume, suited for bigger tanks or ongoing reef systems. The formula supports robust growth and stable water chemistry across all corals, with emphasis on maintaining the essential calcium, magnesium, and carbonate balance. The larger supply reduces the frequency of salt mix purchases and helps ensure consistent salinity management for extended coral health. As with all reef salts, regular testing of calcium, magnesium, alkalinity, and salinity is advised to optimize results and prevent fluctuations that could stress corals.
Red Sea Reef Energy Plus 1000ml

Reef Energy Plus 1000ml extends the benefits of the all-in-one coral food with a larger volume for hobbyists managing larger or multiple tanks. It supports automatic dosing systems, enabling steady nutrient delivery that aligns with coral growth demands. The formulation is designed to foster rapid, healthy growth across soft corals, LPS, SPS, and non-photosynthetic species, while maintaining color and vitality. As with the 500ml variant, care should be taken to follow dosing guidelines to avoid nutrient imbalances and potential algal blooms in systems with limited water turnover.
Buying Guide: Key Purchase Considerations for Red Sea Reefkeeping
When selecting components for a Red Sea reef aquarium, consider the following factors to balance cost, performance, and long-term tank health:
- System size and compatibility: Choose products that match your tank volume and filtration setup. The ReefATO and reef salts, for example, scale well with mid-sized to larger setups but require adequate space and wiring for automation.
- Automation vs. manual control: Automated top-off and dosing reduce maintenance time but require reliable power and contingency planning in case of equipment failure. A robust app and remote monitoring add resilience.
- Water chemistry management: Reef salts and coral foods are designed to optimize calcium, alkalinity, magnesium, and trace elements. Regular testing (calcium, magnesium, alkalinity, and salinity) helps ensure sustained coral health and color.
- Coral compatibility: Some products prioritize growth and coloration for SPS, LPS, or soft corals. Evaluate your coral mix to select supplements that support your specific reef community.
- Storage and dosing considerations: Automatic dosing formulas can simplify maintenance but require stable environmental conditions. Refrigeration needs and shelf life should be considered for all liquid supplements.
- Cost vs. value: Large-volume salts and repeat-use coral foods offer long-term savings and fewer restocking events. Weigh upfront costs against ongoing dosing and replacement requirements.
- Safety and overfeeding risk: Follow recommended dosage ranges to prevent nutrient buildup, which can trigger algae blooms or ammonia spikes. Begin with conservative dosing and monitor tank response.
These selections provide a cohesive foundation for a Red Sea reef setup, combining automated stability with targeted coral nutrition and reliable salt chemistry. For best results, integrate regular water testing, consistent maintenance routines, and a monitoring plan that aligns with your aquarium’s species and growth stage.
