How long is the best time to increase oxygen in fish ponds? How much is a fish pond aerator?
The better aeration time is from 12:30 to 13:30 in sunny day, from 01:00 to 03:00 or 03:00 to 06:00 in cloudy day, and from 23:00 to 06: 00 in the morning before floating head or in continuous rain. The price of general fish pond aerator is 2000-8000 yuan per unit.
1. How long is the better time to increase oxygen in fish ponds
The better aeration time on sunny days is from 12:30 to 13:30, on cloudy days is from 01:00 to 03:00 or from 03:00 to 06:00, and in continuous rainy weather is from 23:00 to 06 o'clock before floating head.
How much is a fish pond aerator
The price of fish pond aerator is 2000-8000 yuan / Taiwan, there are four common methods of fish pond aeration, the first is equipped with aerator, commonly used water wheel aerator or turbine aerator, the second is equipped with bottom tube aeration, generally using micropores and nano-pores, the third is chemical oxygenation, which will be put into sodium carbonate and calcium peroxide, and the fourth is biological aeration to cultivate diatoms, algae and Chlorella.
Matters needing attention in using aerator in fish ponds
1. Start the aerator at noon on a sunny day
There is a big difference in temperature between the upper and lower water layers in the fish ponds at noon on a sunny day, and the oxygen in the lower water can not be replenished in time, so when the aerator is started in time, the upper and lower water can be exchanged, and the temperature difference and oxygen difference can be reduced. Oxygen in the lower water can be replenished in time.
2. Start the aerator in the early morning on cloudy days
On cloudy days, the intensity of sunshine in the early morning is weak, the oxygen production by photosynthesis of phytoplankton in fish ponds is relatively less, and the condition of dissolved oxygen in the whole water body is very poor, so turning on the aerator in the morning with relatively low dissolved oxygen point can effectively solve the phenomenon of "fish floating head" caused by lack of oxygen in the water before and after dawn.
3. Start the aerator in the middle of the night on a rainy day
Generally in continuous rainy days, due to the lack of sunshine for a long time, the photosynthesis of phytoplankton in fish ponds makes less oxygen, which needs to be turned on in the middle of the night to avoid the death of fish ponds.
4. Do not turn on the aerator in the evening
Generally speaking, when the sun sets, the photosynthesis of phytoplankton in fish ponds will stop and oxygen will no longer be supplied to the water. if the aerator is turned on at this time, the dissolved oxygen in the upper water will be reduced and can not be replenished. the dissolved oxygen in the lower water will be consumed very quickly, accelerating the rate of oxygen consumption, and the phenomenon of "fish floating head" is more likely to appear in the early morning of the next day.
5. How long it takes to start
The time to open the aerator in the middle of the night should be long, and the noon should be short; the time to open the aerator in muggy weather should be long, and the cool weather should be short; the time to open the aerator after fertilization should be long, but it should be short when it is not fertilized; the time to open the aerator in wind hours should be long, and when the wind is strong, it should be short. At the same time, it is necessary to increase oxygen to fish ponds at ordinary times, which is conducive to improving water quality.
