The advantage of using a microporous aeration disc

Microporous bottom aeration produces small bubbles that rise slowly with a large water-contact surface, raising dissolved oxygen throughout the water column. It completely changes bottom hypoxia, accelerates oxidation of organic matter and reduces harmful gas damage — lowering disease probability. Working noise is low, so farmed species show no stress response; vitality and feed intake increase, growth speeds up and the breeding cycle shortens. Benefits reported by users include: higher stocking density and yield; better water quality with far fewer disease outbreaks; better product quality; omnidirectional silent oxygenation without stress; effective DO increase in the anoxic layer; and reduced ammonia, nitrogen, chloride and other harmful substances. Compared with mechanical surface aerators — which stir only the surface, can injure fish and shrimp, and cannot reach the hypoxic bottom — microporous aeration is powered from the shore and works from the bottom up. The rising airflow also prolongs feed suspension time, improving feed utilization, and user experience shows it can save about 80% of electricity.
