Why Choose a SeaTorch Calcium Reactor?

Engineered for Performance, Not Just Function

A calcium reactor isn’t just about dissolving media—it’s about how efficiently and consistently it does it.

SeaTorch calcium reactors are designed with an optimised internal flow path, ensuring every drop of water is fully utilised. Instead of water bypassing media (a common issue in standard reactors), the SeaTorch design forces complete circulation and contact, delivering maximum efficiency with less CO₂ waste.

Signature Internal Flow Design

Our central flow system (red pipe design) is not just for aesthetics—it’s engineered to:

• Drive water upward through the chamber
• Return it evenly through the core
• Eliminate dead zones and channeling
• Maximise CO₂ absorption and media dissolution

Stability You Can Rely On

SeaTorch calcium reactors are built to deliver:

• Consistent alkalinity and calcium output
• Minimal fluctuation once dialled in
• Smooth, predictable performance for SPS systems

Precision Build Quality

• High-grade materal for durability and clarity
• Precision fittings and seals to prevent leaks
• Clean, professional construction suited for serious reef systems
• DC pump in build for fine tune

Whether you're running a mixed reef or SPS-dominant system, SeaTorch reactors are designed to handle:

• High calcium demand
• Long-term continuous operation
• Heavy bioload environments

SeaTorch Calicum Reactors available in 4L to 12L+ models. Fully modular add-on media chamber system. Easily scale capacity as coral demand increases. 

SeaTorch calcium reactors give you the flexibility to build a filtration system that evolves with your reef.
