Скачать или смотреть How RAS Reuses Water Without Pollution: The 3-Stage Fish Farming Filtration Secret

Want to reuse the same water for fish farming without polluting your pond?
Recirculating Aquaculture System (RAS) uses a 3-stage filtration process that keeps your water clean and your fish healthy:

1. Mechanical Filtration – removes fish waste and solid particles.


2. Chemical Filtration – balances pH and water hardness.


3. Biological Filtration – breaks down toxic ammonia using good bacteria.
Plus, aeration adds dissolved oxygen for better fish growth and breeding.
No more smelly ponds. No more wasted water. Just clean, efficient catfish farming!
