Forse più adatti ad un animale che non scava e butta tutto in giro Review: Great Drainage Layer for Terrariums - These HydroBalls are a great base layer for terrariums. I use them under substrate to create drainage, and they really help keep excess water away from the main soil layer while still maintaining the right humidity levels. They’re lightweight, easy to rinse before use, and spread evenly across the bottom of a tank. They also work well with a mesh layer on top to keep soil from mixing in, and I’ve noticed the difference in keeping the enclosure cleaner and healthier for my reptiles. The 2.5 lb bag doesn’t go super far if you have a large tank, but for smaller terrariums or as a starter it works well. Overall, they do exactly what they’re meant to and are a simple, effective way to improve drainage in naturalistic or bioactive setups. ## Features - Add water to HydroBalls to increase humidity levels for all tropical reptiles - Use HydroBalls and Mesh for landscaping real plants - keeps plants in place - Use HydroBalls with a pump to create a waterfall and generate water flow for optimum filtration - Hydro balls expanded clay terrarium substrate ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00167TXY0 | | Allergen Information | Gluten Free | | Best Sellers Rank | #52,728 in Pet Supplies ( See Top 100 in Pet Supplies ) #203 in Reptile & Amphibian Food | | Brand | Zoo Med | | Brand Name | Zoo Med | | Customer Reviews | 4.6 out of 5 stars 1,426 Reviews | | Global Trade Identification Number | 00097612720105 | | Included Components | Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds | | Item Form | Granules | | Item Type Name | Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds | | Item Weight | 2.55 Pounds | | Item form | Granules | | Item weight | 2.55 Pounds | | Liquid Volume | 4 Liters | | Liquid volume | 4 Liters | | Manufacturer | Zoo Med Laboratories | | Manufacturer Part Number | VC-10 | | Model Number | VC10 | | Number of Packs | 1 | | Pet Type | Reptile | | Target Species | Terrarium Species | | UPC | 097612720105 | | Unit Count | 1 Count | | Unit count | 1 Count | ## Product Details - **Brand:** Zoo Med - **Item form:** Granules - **Item weight:** 2.55 Pounds - **Liquid volume:** 4 Liters - **Manufacturer:** Zoo Med Laboratories ## Images ![Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Image 1](https://m.media-amazon.com/images/I/81KA7q62mQL.jpg) ![Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Image 2](https://m.media-amazon.com/images/I/91v3xydCgqL.jpg) ![Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Image 3](https://m.media-amazon.com/images/I/81j0cJkozWL.jpg) ![Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Image 4](https://m.media-amazon.com/images/I/41EXrtO6k4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Acquistate per teca *by A***R on 19 January 2025* Acquistate per una teca per tarantola, a lei non sono piaciute e le ha sparse in giro per tutta la teca.

If you tank is larger then you will need another bag! In terms of functionality its great! Holds the water where you want it. ## Frequently Bought Together - Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Zilla Reptile Terrarium Bedding Substrate Jungle Mix, 8 Quart - Zoo Med Naturalistic Terrarium Mesh, 18 x 18-Inches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/387508398-zoo-med-hydroballs-lightweight-expanded-clay-terrarium-substrate-2-5](https://www.desertcart.tn/products/387508398-zoo-med-hydroballs-lightweight-expanded-clay-terrarium-substrate-2-5) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-07*
