ReefBiome: Concentrated Microbial Support for Reef Aquariums
ReefBiome is a concentrated dry microbial blend that helps reef aquariums stay biologically stable. It supports the natural breakdown of organic waste, which helps keep water clear and clean.
ReefBiome contains no added sugars or aggressive carbon sources, so it fits easily into any routine maintenance schedule.
Key Benefits

- Biological Stability: Supports a balanced, well-established microbial community in new and mature systems alike.
- Water Clarity: Helps keep water clear and clean by supporting the steady breakdown of organic matter.
- Gentle Formulation: Free of added sugars and aggressive carbon sources, making it suitable for continuous weekly use.
- Integrated Reef Care: Works alongside your existing filtration and nutrient-management methods.
