MOLT & MOSS NEOCARIDINA DECISION CARD Version: 1.0 Reviewed: 2026-08-12 Topic: Cycle and commission a shrimp tank Situation: You need to decide whether a new or changed system is ready for shrimp. Observe first: Check the complete system, current nitrogen results, test resolution and whether conditioned media and surfaces are actually present. First action: Run the documented nitrogen-processing challenge before livestock arrive rather than using tank age, appearance or a product label as readiness. Record next: Record the added challenge, reporting basis, elapsed time, ammonia and nitrite results, temperature, pH and any intervention. Stop boundary: Do not add shrimp while the intended load is not processed at the declared test resolution or while the system is still changing.
