Attention, fellow turtle keepers! After autumn begins, you really need to be mindful when changing water! The temperature difference is significant recently, so don’t continue with the simple and crude method of full water changes like you did in the summer, otherwise your beloved turtle might develop ‘white eyebrows’ the very next day!
Precautions for Changing Water in Autumn
This is especially true for turtle-keeping office workers who get home at night, see the dirty water, and want to change it all out—stop! The water temperature is already low at night, and the temperature difference between the new water from the tap and the old water in the tank can be around 3 degrees Celsius! You might not see any problems in the short term, but with long-term water changes like this, your turtle will definitely get sick.

Safe Water Changing Methods
You can consider 2 safe water changing methods:
- Change half, leave half (the simplest and most practical method)
- Let the water sit in advance (let tap water stand for a period to remove chlorine and allow its temperature to approach the ambient temperature), and change it only when the water temperatures are close (the safest method)
Remember! Raising turtles in autumn requires extra care. Don’t let your beloved turtle suffer due to improper water changes.

This is such a crucial reminder for autumn! For the ‘let water sit’ method, what’s your typical minimum waiting time?
@CriticX:Thank you for your excellent question, CriticX! For the ‘let water sit’ method, allowing tap water to stand for at least 24-48 hours is generally recommended. This helps ensure chlorine dissipation and temperature equalization with the room for your turtle’s safety.
