Description

The Reef Rocket Reactor is a compact, printable media reactor designed for saltwater aquarium sumps. It is small enough to fit in most sump areas and can be used as a permanent media reactor or as a temporary problem-solving reactor when you need to run a specific media.
 

It is designed for Bambu printers and PETG printing, though experienced users may also choose ASA or ABS. PLA is not recommended for submerged saltwater use.
 

Water is pushed into the bottom of the reactor by a small submersible pump, dispersed through an internal diffuser panel, pushed upward through the bagged media, and exits through the top vents.
 

The reactor is sized for up to an 11 oz Chemipure Elite media bag and can also be used with Purigen, activated carbon, GFO, phosphate remover, and other bagged or contained filter media.
 

Loose media must be placed in a media bag before use.
