How much does a pond aerator cost? A detailed guide to the best aeration times
AbstractThe best aeration time on sunny days is from 12:30 noon to 13:30 in the afternoon; on cloudy days, the best aeration time is from 01:00 to 03:00 or 03:00 to 06:00 in the second half of the night or early the next morning; during continuous rainy weather, the best aeration time is before fish gasp for air or from 23:00 at night to 06:00. Generally, the price of a pond aerator is 2000-8000 yuan per unit.
I. How long is the best time for pond aeration
Generally, the best aeration time on sunny days is from 12:30 noon to 13:30 in the afternoon; on cloudy days, the best aeration time is from 01:00 to 03:00 or 03:00 to 06:00 in the second half of the night or early the next morning; during continuous rainy weather, the best aeration time is before fish gasp for air or from 23:00 at night to 06:00.
II. How much does a pond aerator cost
The price of a pond aerator is 2000-8000 yuan per unit. There are four commonly used methods for pond aeration. The first is to equip an aerator, commonly a paddlewheel aerator or a turbine aerator; the second is to equip bottom-pipe aeration, generally using microporous aeration and nano-microporous aeration; the third is chemical aeration, adding sodium carbonate, calcium peroxide, etc.; the fourth is biological aeration, cultivating diatoms, algae and chlorella.
III. Precautions for using an aerator in a pond
1. Turn on the aerator at noon on sunny days
At noon on sunny days, the temperature difference between the upper and lower water layers in the pond is relatively large, and the oxygen in the lower layer cannot be replenished in time. Therefore, turning on the aerator at the right time can allow the upper and lower water layers to exchange, reduce the temperature difference and oxygen difference, and allow the oxygen in the lower layer to be replenished in time.
2. Turn on the aerator in the early morning on cloudy days
In the early morning on cloudy days, the intensity of sunlight is weak, the photosynthesis of phytoplankton in the pond produces relatively little oxygen, and the dissolved oxygen status of the entire water body is very poor. Therefore, turning on the aerator in the early morning when the dissolved oxygen point is relatively low can effectively solve the “fish gasping for air” phenomenon caused by water body hypoxia around dawn.
3. Turn on the aerator at midnight during continuous rainy days
Generally, during continuous rainy days, due to the lack of sunlight for a long time, the photosynthesis of phytoplankton in the pond produces relatively little oxygen, so the machine needs to be turned on at midnight for aeration to prevent fish from dying from pond turnover.
4. Do not turn on the aerator in the evening
Generally, when the sun sets, the photosynthesis of phytoplankton in the pond stops and no longer supplies oxygen to the water. If the aerator is turned on at this time, the dissolved oxygen in the upper water layer will decrease and cannot be replenished, and the dissolved oxygen in the lower water layer will be consumed very quickly, accelerating the rate of oxygen consumption, making the “fish gasping for air” phenomenon more likely to occur early the next morning.
5. Length of operation time
The time for turning on the aerator at midnight should be long, and at noon it should be short; in hot and stuffy weather, the time for turning on the aerator should be long, and in cool weather it should be short; after fertilizing, the time for turning on the aerator should be long, and when not fertilizing it should be short; when the wind is light, the time for turning on the aerator should be long, and when the wind is strong it should be short. At the same time, in normal times, the pond needs to be aerated at intervals, which helps improve water quality.
