Nitrate and phosphate control gets significantly harder at commercial scale, where bioload and system volume both dwarf home-tank levels. The Reef Octopus Commercial BioChurn line spans four sizes, rated from 1,250 up to 7,500 gallons.
Why Commercial Nutrient Export Needs Its Own Equipment
The same churn-plate biopellet approach that works in a home reef tank scales poorly without purpose-built equipment — commercial systems need reactors engineered for continuous operation at genuinely large media volumes and flow rates.
Choosing a Size
- BC-05T — built for public aquariums, fish farms, and aquaculture centers up to 1,250 gallons.
- BC-10T — steps up commercial capacity to 2,500 gallons.
- BC-20T — rated for systems up to 5,000 gallons.
- BC-30T — the largest in the commercial BioChurn line, rated up to 7,500 gallons.
What to Plan For
- Pairing with the correctly-sized Water Blaster pump for your specific commercial reactor model.
- Facility-scale plumbing and mounting infrastructure for continuous commercial operation.
- Professional installation, standard for equipment at this scale.
