Fluidized Calcium Reactor PF 501 – Deltec

The Deltec PF 501 Calcium Reactor is a high-performance system designed to maintain stable calcium and alkalinity levels in marine aquariums. Using the fluidized bed method, the reactor ensures optimal dissolution of specialized granulate, delivering consistent supplementation for reef tanks. Its innovative design maximizes efficiency and reliability, making it ideal for hobbyists who require precise control over water chemistry in SPS, LPS, and mixed reef environments. By maintaining stable parameters, the PF 501 supports coral growth, overall aquarium health, and long-term system stability.

Fluidized Bed Technology

The Fluidized Calcium Reactor PF 501 – Deltec operates with the fluidized bed method, which allows the use of a specialized granulate.1 This granulate, combined with the reactor’s patented shape, provides a high operating surface area for water to interact with the media. The fluidized bed enables efficient calcium and alkalinity dissolution, ensuring uniform chemical balance throughout the aquarium. Constant granulate motion prevents stagnant zones common in conventional reactors and maximizes contact between water, granulate, and CO₂, leading to stable water parameters and healthier corals. This continuous tumbling of media is key to preventing channeling and ensuring every part of the granulate is exposed to the water flow.

Optimal Granulate and CO₂ Combination

A major advantage of the PF 501 is its optimized combination of granulate, water, and CO₂. This setup allows controlled dissolution of granulate particles, releasing calcium and alkalinity steadily. The reactor’s patented design maximizes the operating surface, increasing efficiency compared to traditional reactors. By maintaining the ideal balance of media, water flow, and CO₂ concentration, aquarists can ensure stable water chemistry even during periods of high coral growth or nutrient demand. This delicate balance is what separates a good reactor from a great one, ensuring your aquarium's needs are met precisely

Self-Cleaning Design

The PF 501 features a self-cleaning mechanism that prevents sludge and residue buildup. In conventional reactors, compaction or accumulation of unreacted granulate can reduce efficiency. The fluidized bed keeps granulate in continuous motion, minimizing dead zones and maintaining consistent dissolution. This self-cleaning function reduces maintenance needs while keeping performance at its peak over extended periods. This design saves you time and effort, as you won't need to manually stir the media as often.

Automatic Degassing and Gas Management

Processing gases, especially CO₂, can interfere with calcium dissolution. The PF 501 includes automatic degassing to remove excess gases. Additional features include a bubble counter to monitor CO₂ flow, a check valve to prevent backflow, and connections for electrode and gas manifold measurement.2 These allow precise monitoring and adjustment of reactor performance, ensuring accurate dosing of calcium and alkalinity for any reef system. This comprehensive gas management system ensures the reactor operates at peak efficiency

Optional CO₂ Solenoid Valve

For further automation, the PF 501 can be equipped with an optional solenoid valve to regulate CO₂ flow.3 Available for all PF reactors from the PF 501 onward, it automatically adjusts CO₂ input based on aquarium demand. This reduces manual intervention, increases efficiency, and is particularly useful in fully automated reef setups requiring stable parameters. This solenoid valve works seamlessly with most aquarium controllers, providing a plug-and-play solution for advanced hobbyists.

Reliability and Efficiency

Thanks to its design, the PF 501 delivers reliable calcium supplementation while minimizing maintenance. Its fluidized bed system, self-cleaning functionality, and gas management features ensure that reef tanks receive proper calcium and alkalinity levels without constant monitoring. Aquarists can focus on other aspects of reef keeping while maintaining a healthy, thriving ecosystem. The robust construction and high-quality materials guarantee long-lasting performance, providing peace of mind to the serious aquarist.
