💡 Did You Know?
🚫 Avoid touching the sensor – Skin oils can reduce sensitivity
🚫 Do not clean with bleach, detergents, or abrasive materials
✅ To remove algae, gently wipe with a soft, clean material
✅ Check sensor response by holding it over an ammonia bottle – it should rapidly change color
✅ Drying out does not permanently damage the sensor – Sensitivity may even improve over time
