Overview
The Two Little Fishies Phosban Reactor 550 is an upflow media reactor built to get the most from GFO and other chemical filter media. Water enters at the bottom and rises through a dispersion plate, spreading flow evenly across the media bed. This even distribution prevents channeling and maximizes media contact for better results.
Key Features
- Upflow design for highly efficient media usage
- Dispersion plate spreads water evenly across the bed
- Prevents channeling that wastes filter media
- Compatible with GFO and other chemical media
- A trusted reactor for reef and marine systems

Frequently Asked Questions
What media can I run in this reactor?
It is designed for GFO and works well with other granular chemical filter media.
Why does the upflow design matter?
Pushing water upward through a dispersion plate keeps flow even and stops channeling, so the media is used efficiently.
