Description
Mantis Tornado Protein Skimmer 200 — In-sump skimmer for large reef systems of 1500 to 2500 litres
Once a reef system passes the 1500 litre mark, many skimmers sized for smaller tanks run flat out just keeping pace with the bioload. Mantis Tornado Protein Skimmer 200 (SKU: MA069103) sits at the larger end of the Tornado range, rated for marine aquariums of 1500 to 2500 litres and powered by a 50 W Mantis Tornado 4000 needle-wheel pump that draws 1500 L/H of air into the reaction chamber.
The body measures about 285 by 230 mm at the base and 640 mm tall, large enough to hold a substantial foam column without the collection cup filling faster than it can be emptied. It keeps the same turbulence-reducing inlet and bubble dispersant chamber as the smaller Tornado models, scaled up to match the higher air throughput, and remains an in-sump-only design built in solid PVC and acrylic that disassembles fully for cleaning. Large display tanks with a heavy fish stock suit the 200 better than the 180 below it, and systems moving past 2500 L step up to the 300. The maker rates the Tornado range as efficient and quiet in operation. The 200 and the 300 have overlapping tank ranges between 2000 and 2500 L, so the choice comes down to stocking density and feeding.
Usage & Application
When to Use
- Large reef displays: Systems of 1500 to 2500 L, display plus sump.
- Heavy fish stocking: Bioloads from fish-dominant tanks rather than coral-only systems.
- Frequent feeding: High feed rates that push dissolved organics up between water changes.
- Replacing an undersized unit: A step up from the 180 where foam production outpaces the cup.
Installation & Setup Guide
- Position in the sump: Install the skimmer in its dedicated section, level on the sump floor.
- Set the operating level: Adjust the sump water level until the foam column holds steady.
- Let it break in: Allow the foam column to stabilise over the first several days of running.
- Service on a schedule: Strip the body down periodically to clean the pump and clear salt build-up.
