The SMR1 is a new media reactor from NextReef which was specially designed to turn over the solid carbon dosing biopellets. We first caught wind of this specialized SMR1 from NextReef back in January and now that it is getting closer to availability, we can finally see what features will make the SMR1 better at turning over biopellets than your run of the mill media reactor. First of all, the SMR1 has a hang-on-the-back lid assembly which will allow it to hang on your tank or sump. Next, the smoked blue acrylic will reduce light penetration allowing the bacteria to grow more prolifically without any light inhibition. Finally, the SMR1 will be able to hold up to one liter of biopellets in a fluidized state.
