Clownfish (Amphiprion percula), is a variety of marine ornamental fish. In rearing ornamental fish, water quality management is required to maintain the optimal condition of water quality. Filtration and recirculation are proven as preeminent ways to manage the optimal condition of water quality in aquarium as the vessel for rearing ornamental fish. Simple recirculation system double bottom filter was applied in this research with treatments of components modification of the system. The objective of the research were to identify the concentration of ammonia and survival rate in rearing media of clownfish (A. percula) using recirculation system double bottom filter with several modification components. The treatments are: 1) no recirculation/aeration only (treatment A), 2) system with components of gravel, activated carbon and Dacron (treatment B) and 3) sand, activated carbon and Dacron (treatment C). The result showed that the ammonia concentration in system A (control) was 8.323 mg/l, system B (gravel, activated carbon and Dacron) was 1.599 mg/l and system C (sand, activated carbon and Dacron) was 0.088 mg/l. The highest value of survival rate was in system C (sand, activated carbon and Dacron) which valued 90%. Water quality was monitored twice daily included water temperature (26.3??27.4 °C), pH (8.27-8.36), dissolved oxygen (4.95-5.30 mg/L) and water salinity (33.0-34.3 ppt). As the conclusion, component sand, activated carbon and Dacron in recirculation system double bottom filter provided better performance in reducing ammonia in rearing media of blue devil (A. percula) which also confirmed with the survival rate value.
