First, the summer water temperature is high, the water body is stratified with the temperature, the bottom of the low temperature dissolved oxygen is low, the water quality is easy to deteriorate. 1. Control the depth of the pond water and control the pool water to 1.2 to 1.5 meters. 2. Open aerators at noon on sunny days to promote the convection of water bodies. Second, in summer, the water temperature is high, the digestion and absorption rate of fish is reduced, the growth rate of fish is slowed, physiological metabolism is poor, and anti-stress ability is decreased. 1. For ponds with drainage conditions, the well water may be added to the pool before or after the noon aeration machine is opened. At the same time, the upper layer of high-temperature water may be discharged by overflowing on the other side of the pond; water may be introduced into the pond without drainage conditions. The upper aquatic plants, such as gourds and duckweed, cover 1/10 of the surface of the water to reduce the temperature of the water. 2. Change the feeding time before 11 o'clock in the morning and after 4 o'clock in the afternoon to avoid the high temperature of the surface water at noon. Third, the summer fish eaten large, some low-quality or contain undesirable substances and hormones feed will seriously affect the breeding effect. 1. Buy quality brand feed. Vitamin C is added to the feed, adding about 300 grams per ton of feed to protect the liver, enhance physical fitness, improve immunity and detoxification. 2. The amount of feed to be fed should not be too much, adhere to 80% fullness principle, in order to avoid the digestion and malabsorption and intestinal diseases caused by overfullness.
Water is vital to human life. Drinking water, swimming pool water, SPA water, aquarium water, pond water, related to the quality of everyone's life, how do you ensure the quality of water? Water quality test strips, of course. These convenient and easy-to-use strips quickly and accurately test for a range of contaminants and keep you and your family safe.

Summer temperatures are high, which are conducive to the growth of aquatic animals, but at the same time they are also the key stages of multiple diseases, high mortality, and difficult management. How to overcome the unfavorable factors, do a good job in the management of pond culture and disease prevention, and improve the breeding efficiency are the issues most concerned to the farmers. The following is a summary of the unfavorable factors caused by the high summer water temperature and its countermeasures:
TEST PROCEDURE
Immerse the strip for 2 seconds and then remove the strip.
Do not shake excess water off, and then hold the strip horizontally for 20 seconds.
Compare against the color chart and read immediately within 30 seconds to get accurate result.
IMPORTANT TO KNOW
1.Test for 30 seconds
When using the water test strip, your results are complete (ready to compare) after dipping the
test strip. Upon completion, make sure to compare your results immediately. The strip is no
longer valid outside of the 30 second testing period Discard the test strip after 60 seconds as
any further color change will be meaningless.
2.Prevent altered results
Here`s what you can do to prevent decreased shelf life of the strip and altered results
Do Store in a cool dry place away from direct sunlight.
Do read the instructions carefully before use.
Do Avoid touching or polluting test areas of the strip.
Do not place wet fingers in the bottle.
Do Keep the cap on tight between use.
Do not remove the desiccant pouch.
3.Primary and Secondary water Regulations
The EPA sets legal limits on over 90 contaminants in water test strip. There are two categories,
primary and secondary. Primary contaminants are substances that can be toxic in small amounts
On the other hand, secondary contaminants are less toxic species and would include cosmetic
issues (color, taste, and odor) of water. These strips test for the most commonly found primary
contaminants lead, fluoride, copper, chlorine, nitrite, nitrate) as well as the most commonly found
secondary contaminants(Copper, Iron, Sulfate, Zinc, Manganese, Fluoride, Chloride, and pH)
