Swirl Filter
Swirl as in cyclone. Design rationale:
- Pump water in parallel to bucket side so water swirls in bucket, allowing fish waste to settle
- Overflow back to system is in the middle of the bucket. The middle top has least waste.
- Drain valve on bottom to drain waste periodically.
- Water must flow slowly for best results so solids have time to settle.
