To maintain water quality, regular maintenance is crucial. Test the water regularly for pH, ammonia, nitrite, and nitrate levels. Keep the pond clean by removing debris and excess organic matter.
Use beneficial bacteria to control organic waste and prevent nutrient buildup. Install an appropriate filtration system that suits the size and needs of your pond.
Consider using plants to naturally filter the water and provide oxygen. Avoid overfeeding fish to minimize waste. Lastly, ensure proper circulation and aeration to maintain a healthy balance of oxygen and carbon dioxide in the water.
