Nextreef SMR1 Solid Media Reactor - Holds up to 1 Liter of NP Biopellets. 

  • Recommended flow rate: 350 GPH
  • 5/8" input/output with hose barb fittings and sump mounting bracket.

Developed in conjunction with Aquarium Specialty, the US Distributor of NP BioPellets and NextReef.  The SMR1 is the first media/substrate reactor specifically designed for long term use of larger media.

Evolved from our MR1 Media/Substrate Reactors, the NextReef SMR1 fills a specialized role while retaining the quality and ease of use you'd expect from a NextReef reactor.

Available in two sizes:  

  • SMR1 is 16" tall overall, with a 14" reaction chamber.
  • SMR1 XL is 23" overall with a 21" reaction chamber.

The NextReef SMR1 is based on our standard MR1 media/substrate reactors, but with some significant changes...

Cast blue acrylic for the main body .  Made specially for us, it's both thicker and stronger than our standard tubing.  The translucent blue color also serves an important purpose - it keeps out light to reduce algae and opimize beneficial bacterial growth.   They're great in lighted sumps, or anywhere light exposure is a concern.

Modified internal plenum assembly.   Our original design works great with sponges and small media - the SMR1 eliminates the sponges to reduce maintenance.  Since BioPellets and Zeolithic media are designed for long term use, reducing maintenance fosters system stability .

Higher flow rates and reduced head pressure .  The SMR1 comes set up to use larger fittings than our original reactors, so it  flows more water with less restriction .  The NextReef SMR1 flows enough water to easily fluidize larger media.

The SMR1 features plenums laser-cut from 3/16" acrylic.  They're thick, they're heavy, they're strong... and they flow great.

Every NextReef Reactor is hand-crafted in the USA from the highest quality materials, and CAD engineered / CNC cut for a precise fit.
