CONCLUSION
Nannochloropsis is the cornerstone phytoplankton species for reef aquaria, powering the food web from the bottom up. Its EPA-rich profile makes it indispensable for sustaining copepods and filter feeders.
FREQUENTLY ASKED QUESTIONS
Q: What makes Nannochloropsis important for reef tanks?
A: It is rich in EPA fatty acids and forms the base of the food chain.
It supports copepods, clams, and filter feeders while improving water quality.
Q: Can fish eat Nannochloropsis directly?
A: No, most fish cannot ingest particles this small. Instead, it feeds copepods and microfauna, which in turn feed your fish.
Q: How often should I dose Nannochloropsis?
A: Daily or several times per week, depending on tank density and feeding needs. Consistent dosing helps sustain copepod populations.
Q: Does Nannochloropsis remove nutrients from the water?
A: Yes, it uptakes nitrate and phosphate, helping to balance water quality in reef aquaria.
