Review: Acquistate per una teca per tarantola, a lei non sono piaciute e le ha sparse in giro per tutta la teca. Forse più adatti ad un animale che non scava e butta tutto in giro
Review: 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.

Just about covered the base of a 30x30cm floor space tank with a 2inch layer. If you tank is larger then you will need another bag! In terms of functionality its great! Holds the water where you want it.
