5 Steps to Introduce into a Fish Tank
How to Safely Add This PETG Decoration to Your Aquarium:
Inspect the Item:
Ensure there are no loose strings or sharp edges. Sand lightly if needed.
Rinse Thoroughly:
Rinse the decoration under warm water (no soap or chemicals) to remove any dust or residue.
Optional: Soak in Tank Water:
Let it soak in a container of aquarium water for 24–48 hours. This helps to equalize temperature and water chemistry.
Check Fit and Placement:
Gently place it in your tank. Avoid pinching live plants or trapping fish.
Observe Fish Behavior:
Monitor your pets to ensure they interact well with the new decor. Most will begin using it as a hideout shortly.
