Hydroton (Hydroballs) — Expanded Clay Drainage Layer for Vivariums & Hydroponic Setups Description: Our drainage layer of choice. Hydroton are expanded clay balls that absorb and release water evenly, promote high levels of aerobic bacteria growth (the good stuff!), and provide an excellent negative space to trap water in the drainage layer. This is the same material many hydroponic shops use for growing plants. Why builders love Hydroton: Even water absorption & release — Expanded clay balls regulate moisture throughout the drainage layer Aerobic bacteria growth — High surface area promotes beneficial bacteria that keep the system healthy Negative space — Excellent structure for trapping water without waterlogging the substrate Hydroponic-grade material — Same trusted material used by hydroponic growers Reusable — Rinse and reuse for ongoing builds Recommended amounts by enclosure size: Enclosure Size Bags Needed 10 gallon 2 bags 12x12 1.5–2 bags 20 gallon 3–4 bags 18x18 3–4 bags 40 gallon breeder 5–6 bags 24x18 4–5 bags 36x18 5–6 bags 55 gallon 6–7 bags Directions: Pour 2–3 inches of Hydroton into the bottom of your enclosure as the drainage layer before adding substrate barrier and substrate.
