When it rains, if wind and rain protection measures are not taken around the outer pool, the acid-base content in the rainwater will inevitably directly affect the water quality in the turtle pond.

Turtles are mainly aquatic turtles like stone. Money likes weakly alkaline water, and tap water is weakly alkaline, which basically meets the water quality requirements of this type of turtle. The pH of surface water such as rainwater is relatively low. If you build a pond to raise turtles on a rooftop or outdoors, you must use plastic film or other rainproof materials to block the rainfall to avoid contamination of the water in the turtle pond due to rainfall.

When the water quality is abnormal, such as when the pH exceeds the normal range (6.5-8.5), there is heavy rain, or the water is turbid due to other factors, the water must be changed. Before changing the water, test the pH of the turtle pond water. Adjust the pH first or let it sit in the sun for two or three days, and then change it after the water quality stabilizes.

If it is a turtle pond that has been bred for too long and there is too much silt accumulated in it, before changing the water, first remove the silt, clean the bottom of the pond, and sprinkle a little quicklime. When changing the water, do not use too much water to wash the turtle, and do not touch the turtle with a broom forcefully to prevent the turtle from being frightened or injured. When changing the water, pay attention to flushing and cleaning the surroundings of the turtle pond.

After testing the pH of the water, if it is too low, it is too acidic. Or water that is too large or too alkaline needs to be artificially adjusted to ensure that the turtles live in the best condition.

When PH>8.5, it indicates that the water quality is alkaline. The PH is too high either because of the local water quality itself or because the water body is polluted by alkaline substances. The ammonia nitrogen content and toxicity of alkaline water will also increase accordingly. Improper treatment can easily cause turtle poisoning or rotten skin and nail rot.

So what is the adjustment method? First use mechanical Add oxygen or change water, and then sprinkle PH adjuster. If the pH of the local water quality is too high and remains high, non-toxic weakly acidic substances such as acetic acid should be used to lower the pH before use to prevent alkali or ammonia poisoning of turtles.

When PH<6.5, it indicates that the water quality is acidic. The PH is too low either because of the local water quality itself or because the water body is polluted by acidic substances. When turtles live in acidic water, their immunity will be reduced and they are easily infected or infected with diseases. Even if there is no lack of oxygen in the water, they will have difficulty breathing, their feed digestion and absorption rate will be low, and their growth will be slow. The adjustment method is to sprinkle quicklime or baking soda.

Precautions for breeding tortoises on rainy days

1. Reasonable arrangement of water levels

In winter, the water level in tortoise outer ponds is generally controlled to be relatively low. If it rains in spring, If the water level does not rise suddenly, then it is a good thing that the water level in the turtle pond slowly increases naturally. However, we should pay attention to acid rain in Guangdong. A large amount of acid rain enters the pond and directly reduces the PH value, causing turtle stress. It also destroys the balance of bacteria and inhibits ammonia nitrogen, nitrite, etc. Transformation of harmful substances; at the same time, in rainy weather, the dissolved oxygen in the water body decreases, and if it is not treated in time, the probability of poisoning increases.

2. Understand the ecosystem and maintain it properly

In rainy weather, the light is weak, and the photosynthesis of phytoplankton in the water body is weakened; rainwater exchanges with pond water, causing feces and residual bait at the bottom of the pond, etc. The emergence of organic matter causes an increase in the oxygen consumption of the water body; the low air pressure in rainy weather reduces the oxygen dissolved in the surface water body, resulting in insufficient dissolved oxygen in the water body, resulting in the accumulation of ammonia nitrogen, nitrite and other harmful substances in the pond water body; heavy rains cause ponds to The water temperature and pH value change greatly, and aquatic organisms are prone to stress reactions.

Therefore, anti-stress agents such as VC should be splashed in time after rain For medicines, after the weather clears, oxidation-type primers or biological agents should be poured in time to adjust the water quality, and the oxygenator should be turned on at the right time to implement physical oxygenation; after the weather clears, the feeding time can be advanced appropriately, and an appropriate amount of vitamins and immune enhancers can be added to the feed. , enhance the turtle's disease resistance.

3. Prevention of specific diseases

Continuous rainy weather in spring can easily cause harmful bacteria to multiply and induce diseases, especially ciliated parasitic diseases and saprolegnia. Ponds must be disinfected Treatment to prevent the occurrence of saprolegnia. Water bodies should be disinfected and insecticided promptly after rain and sunny days, and probiotics should be replenished in a timely manner to maintain the balance of pond bacteria and algae.
