Frequently Asked Questions

Q: Are expanded clay pebbles safe for fish tanks and aquatic life?

A: Yes! These expanded clay pebbles are pH-neutral and contain no harmful chemicals, making them completely safe for fish, shrimp, and other aquatic life. They are widely used as a substrate in aquaponics and planted aquarium setups.

Q: Can I reuse expanded clay pebbles?

A: Absolutely. One of the biggest advantages of expanded clay pebbles is that they are fully reusable. Simply rinse them thoroughly with water, optionally soak in a diluted hydrogen peroxide or bleach solution to sterilize, rinse again, and they're ready for a new growing cycle.

Q: How do I use expanded clay pebbles for succulents?

A: For succulents, place a layer of expanded clay pebbles at the bottom of your pot as a drainage layer before adding your potting mix. This prevents water from pooling at the roots and greatly reduces the risk of root rot — a common issue with succulents.

Q: Do I need to rinse expanded clay pebbles before first use?

A: Yes, it is recommended to rinse the clay pebbles thoroughly before use to remove any dust or loose clay particles. Soak them in clean water for several hours or overnight for best results, especially before adding them to a fish tank or hydroponics system.
