Mantis Tornado Protein Skimmer 800 The Mantis Tornado Protein Skimmer 800 is a commercial-grade in-sump protein skimmer designed for very large marine and reef aquarium systems between 6,000 and 8,000 litres. Featuring the powerful Mantis Tornado 12000 DC pump, the Tornado 800 produces an impressive 5,500 litres of air per hour, generating an extremely dense column of ultra-fine bubbles for maximum foam fractionation and nutrient export. Its oversized reaction chamber, turbulence-reducing body and bubble dispersant plate maximise contact time between air and water, allowing dissolved organic compounds to be efficiently removed before they break down into ammonia, nitrate and phosphate. Manufactured from premium PVC and acrylic, the Tornado 800 is built for continuous operation in demanding reef aquariums, public aquariums and commercial marine systems. It fully disassembles for straightforward cleaning and routine maintenance.

The Tornado 12000 DC pump draws aquarium water and air into the large reaction chamber, producing millions of ultra-fine bubbles. Organic waste attaches to these bubbles and rises into the oversized collection cup, removing proteins and dissolved organic compounds before they can negatively impact water quality. This process helps maintain excellent water clarity, stable nutrient levels and optimal conditions for marine fish and corals. What Aquarium Size Is the Tornado 800 Rated For? The Mantis Tornado Protein Skimmer 800 is designed for marine and reef aquarium systems between 6,000 and 8,000 litres. Its high air intake and large reaction chamber make it ideal for heavily stocked reef aquariums, commercial holding systems and public aquarium displays where reliable nutrient export is essential. Why Use a Protein Skimmer? Protein skimmers remove dissolved organic compounds before they decompose, helping to: Reduce nitrate and phosphate Improve water clarity Increase oxygen exchange Reduce nuisance algae Promote healthier fish and corals Improve long-term reef stability Reduce the load on biological filtration Why Choose the Mantis Tornado 800? The Mantis Tornado 800 is engineered for aquarists and commercial facilities requiring maximum skimming performance. Its exceptional air intake, oversized reaction chamber and powerful DC pump provide efficient nutrient export while maintaining quiet, reliable operation. With robust PVC and acrylic construction and a fully serviceable design, the Tornado 800 is built to provide years of dependable performance on the largest marine aquarium systems.
