Methods to deal with a turtle that has a strong odor:

1. Change the water frequently. After each feeding to the turtle, it is best to clean the food residue and turtle feces in the water, and then replace a quarter of the water in the turtle tank to keep the turtle tank clean.

2. Avoid mixed culture. Do not mix turtles with fish and shrimps. Just keep turtles alone. This will facilitate the maintenance of the turtle tank and avoid the rancid smell caused by the death of fish and shrimps.

3. Get some sun exposure. Let the turtle bask in the sun for two to three hours every day. After the tortoise shell is sterilized, bacteria will not easily breed, and the turtle's body will not stink.

4. Clean the turtle. Use toothpaste to clean the turtle's body. Squeeze the toothpaste on the toothbrush, then gently brush the turtle's carapace and plastron, then rinse them with water. Note that the toothbrush should have soft bristles to avoid hurting the turtle.

5. Isolation and disinfection. If the turtle is suffering from nail rot and is smelly, you can first isolate the sick turtle, remove the rotten flesh from the injured area, then scrub the injured area with hydrogen peroxide, and then apply potassium permanganate crystal powder.

6. Put activated carbon in the turtle house. Activated carbon has a good odor removal effect. If it is a larger piece of activated carbon, it can be tied together with decorative stones and sunk to the bottom of the pool. This can increase the adsorption of odorous substances in the pool by the activated carbon.
