Fish Feed Machine Knowleagde

1. When you raise floating fish feed,it is best to raise some phytoplankton at the bottom of the pond and apply regular fertilizer (for top dressing, phosphorus fertilizer is used, because nitrogen fertilizers are generally not lacking in fish farming with pellet feed) to supplement the lack of phosphorus in the water.

Fertilization principle: Sprinkle after dissolution in the morning to make the phytoplankton use timely.
The purpose of fertilization: to provide adequate nutrition for phytoplankton and promote its growth and reproduction.

2. When farmers raising the fishes how to use aerators scientifically: Start the aerators for 1-2 hours at noon during the day, which can bring the oxygen-rich water from the upper layer of the pond to the bottom layer and reduce the oxygen consumption of the bottom layer at night.(Principle: the water exposure of the bottom layer of harmful substances accelerates the oxidation and decomposition of the bottom layer of organic matter, and reduces the content of ammonia nitrogen, nitrous acid and other harmful substances in the water)
