Why Let Water Sit for Reptiles?
Reptiles, like all pets, require clean, safe water for drinking and soaking. However, tap water contains chlorine and chloramines added to kill bacteria and pathogens. While these chemicals are safe for humans in regulated amounts, they can be detrimental to reptiles' sensitive systems. Letting water sit for 24 hours allows chlorine to dissipate naturally, making it safer for your scaled friend.
The Science Behind Dechlorination
Chlorine is a volatile chemical that evaporates from water over time. At room temperature, approximately 1 ppm (part per million) of chlorine can dissipate within 24 hours, especially if the water is in an open container. However, chloramines, which are more stable, may require additional treatment. For reptiles, simply letting water sit is a simple first step to reduce chemical stress on their skin and internal organs.
Benefits of Letting Water Sit
- Reduces chlorine and chloramine levels – These chemicals can irritate reptiles' skin and eyes, and interfere with beneficial bacteria in their digestive system.
- Allows temperature adjustment – Room temperature water is often better than cold tap water, preventing temperature shock.
- Mimics natural water sources – Stagnant water in the wild often has low chemical levels; aging water replicates this.
How to Properly Age Water
- Fill a clean, open container with tap water.
- Let it sit uncovered for 24–48 hours in a clean area away from dust and contaminants.
- Alternatively, use a water conditioner specifically for reptiles to instantly remove chlorine and chloramines if time is short.
Important: Never use distilled water for reptiles as it lacks essential minerals. Bottled spring water is acceptable but can be expensive. Aged tap water is cost-effective and safe when properly treated.
Water Quality and Reptile Health
Reptiles need water not just for drinking but also for soaking, which aids shedding and hydration. Dirty or chemically treated water can lead to dehydration, kidney issues, and skin infections. Signs of hydration problems include sunken eyes, wrinkled skin, and lethargy. Always provide fresh water daily.
Additional Hydration Tips
- Change water every 24 hours to prevent bacterial growth.
- Use a shallow bowl to prevent drowning, especially for small or arboreal species.
- Mist the enclosure for species that drink droplets (e.g., chameleons).
Common Mistakes to Avoid
- Using water straight from the tap without aging.
- Leaving water in direct sunlight, which can promote algae.
- Adding chemicals like bleach or disinfectants expecting them to purify water—they are toxic.
Letting water sit is a simple, effective practice that supports reptile health and longevity. Combined with proper diet and habitat, it ensures your pet thrives.
