Frequently Asked Questions
Q: What are expanded clay pebbles used for in hydroponics and fish tanks?
A: Expanded clay pebbles are used as a growing medium in hydroponic systems, aquaponic fish tanks, and aquatic plant setups. They provide excellent aeration, drainage, and anchorage for plant roots, while allowing water and nutrients to circulate freely. They are also great for layering at the bottom of succulent pots to prevent waterlogging.

A: Yes! These expanded clay pebbles are made from 100% natural clay with no added chemicals or high-concern substances. They are pH-neutral and non-toxic, making them completely safe for use in fish tanks and aquatic plant environments.
Q: Can I reuse expanded clay pebbles?
A: Absolutely. One of the biggest advantages of expanded clay pebbles is that they are reusable. After each growing cycle, simply rinse them thoroughly with clean water (and optionally soak in a mild hydrogen peroxide solution) to remove debris and sterilise them before reuse.
Q: How do I prepare the clay pebbles before first use?
A: Before using your clay pebbles for the first time, rinse them well under running water to remove any dust or clay particles. Soak them in clean water for a few hours to allow full hydration. This helps ensure they are ready to support your plants from day one.
