Biopellets

What does Biopellets mean?

Biopellets are a slow-release carbon source (typically PHA polymer beads) used to drive nitrate + phosphate reduction via heterotrophic bacterial growth. The bacteria consume both N and P then get exported via skimmer.

How is Biopellets used in aquariums?

Run in a fluidized reactor adjacent to the protein skimmer. Start with half the recommended volume to avoid bacterial blooms; ramp up over 2-3 weeks. Monitor nitrate weekly; if both N and P go to undetectable levels, reduce volume - some nutrients are needed for coral coloration.

How Biopellets fits the bigger picture

Understanding Biopellets matters because it's connected to broader husbandry decisions: equipment selection compounds: skimper + return + dosing all need to match each other and the tank size.
