1. Thoroughly improves bottom-layer oxygen shortage. Bottom-layer oxygen deficiency in a farming water body is one of the main causes of bottom deterioration, water-quality decline, restricted productivity and disease in the stock. With bottom aeration, the total oxygen content of the whole water body rises greatly, and the constant exchange between oxygen-rich surface water and oxygen-poor bottom water makes the dissolved oxygen of the surface and bottom layers converge, greatly improving bottom oxygen conditions. Extensive tests show that in natural farming water bodies, a bottom aeration system raises dissolved oxygen by more than 40% compared with other aeration machinery.
2. Reduces harmful substances in the water. During farming, large amounts of ammonia nitrogen, nitrite, hydrogen sulfide, E. coli, Vibrio and other harmful substances are produced. With bottom aeration, these are greatly reduced thanks to the water turnover and sufficient oxygen at the bottom — especially nitrite and E. coli, which drop most noticeably. Practice proves that a bottom aeration system can completely remove the worry of nitrite hazards.
3. Improves the pond bottom. Bottom quality is crucial to farming, and sediment accumulation is a headache that is hard to solve. A bottom aeration system effectively decomposes and oxidises settled uneaten feed, excreta, moulted shells, sludge and decaying algae, improving bottom conditions and activating the ecological functions of the sediment.
4. Increases natural feed and saves feed input. Bottom aeration promotes the growth of beneficial algae and plankton, increasing natural feed. At the same yield, feed input can be saved by more than 15%.
5. Reduces chemical inputs for pollution-free farming. To adjust water quality, prevent disease and lower farming risk, farmers often use large amounts of chemicals — which pollutes the water and leaves food-safety concerns. With a Roots-blower aeration system, water and bottom quality improve, oxygen is sufficient and the water body stays healthy and stable, so medication can be reduced or even avoided.
6. Breaks water stratification. A Roots blower bottom microporous aeration system creates vertical convection, eliminating stratification of dissolved oxygen, temperature, salinity and algae, reducing the disturbance of air temperature, air pressure and rain on pond-water stability, thereby reducing stress on fish and shrimp and promoting growth. It also reduces water exchange and saves pumping costs.
7. Strengthens the stock's constitution and disease resistance. Because the water body is healthy, the constitution and disease resistance of the stock improve markedly. Repeated practice shows that when ponds all around are suffering disease and mortality, ponds using bottom microporous aeration can effectively delay and shorten the duration and severity of disease — and a considerable number of ponds even prevent disease from occurring.
