Skimz BR153 Monzter Biopellet Reactor

Solid carbon dosing (biopellets) has recently become an extremely popular method of removing nitrates from the aquarium. The exact method of denitrification can be different for each tank but it mainly consists of a few things:

  • Nitrate laden Bacteria is removed via the protein skimmer
  • Bacteria directly converts nitrite into nitrous oxide so nitrate is never produced
  • Bacteria consumes nitrates and processes them down into nitrogen gas
  • Nitrate laden Bacteria is consumed by tank inhabitants like corals and sponges


Depending on the system it should take 4-8 weeks for the bacteria population to multiply and begin its work on your nitrates. Once you have the reactor going we suggest not making any adjustments for 8 weeks. Give the media and bacteria time to adjust to the parameters found in your tank and begin working. The absolute best advice we can give with this system is to set it up and forget about it for two months. Unless something is obviously not right, resist all temptation to make any changes until the two months are up.
