Perfect drainage layer.
This drainage layer has really made a difference. When I tried to go bioactive without a drainage layer I got bugs and my plants died because of moist build up. When I gave it a drainage layer wow it impacted my enclosure and made it so no bugs and my plant flourish.

Works ok
Works well enough as a drainage substrate, I like it alot better than other types as the clay balls are nice and smooth and I don’t have to worry about it scratching or breaking the glass of my geckos tank. The bags are kinda small though so even for a small tank I did end up needing a couple bags, and honestly still could use some more.

Great for a bio active tropical enclosure!
Perfect for the first layer of a bio active tropical enclosure.

Work great
Works great for what I have been using them for a little too great actually bc after a while of using them I had to stop because they dried out my tank too fast. If you have a big tank though and need to try to keep the moisture down Iâd definitely recommend using them tho

Nice size for orchid medium
I bought Zoo Med HydroBalls to use to re-root a phalaenopsis orchid.Other reviewers have commented on the importance of rinsing these wellâthey are absolutely right. These carry an astonishing amount of dust with them. Mine arrived in good condition with no crushed bits. The amount of media you get for the price is excellent (but check with your local pet store if you typically pay shipping on Amazon.com ordersâyou may be able to get them for a similar price). I have been using these for a couple of weeks, so I can’t comment on their durability.What I especially liked about these HydroBalls was their size. They are about 1cm in diameter, or 3/8″. The last time I bought clay spheres, they were between 1/2″ and 5/8″ (which is good if you need more aeration). For my situation, the smaller sphere size is ideal. I think these will retain a bit more water in the winter, when it is very dry and my orchids typically struggle. The HydroBalls mixed well with some of the usual orchid potting medium.Note these will also work well for you if you’re developing a comedy routine, but you’re out of banana peels. If (when) you spill some, make sure you find them with your eyes instead of your feet.

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

Ich habe die Zoomed HydroBalls als unterste Drainageschicht in meinem Terrarium verwendet â und sie erfüllen ihren Zweck absolut zuverlässig. Die Tonkugeln sorgen für eine gute Wasserableitung und helfen, Staunässe im Bodengrund zu vermeiden. In Kombination mit einem Vlies und passendem Substrat darüber entsteht ein stabiles, gut belüftetes Bodenprofil â ideal für tropische Terrarien oder Paludarien.Die Verarbeitung ist gut, die Kugeln sind gleichmäÃig groà und staubfrei, was mir besonders wichtig war. AuÃerdem speichern sie Feuchtigkeit gut und tragen zu einer stabilen Luftfeuchtigkeit bei.Was man aber sagen muss: Der Preis ist im Vergleich zu ähnlichen Produkten etwas hoch. Für kleinere Becken oder Projekte ist das noch vertretbar, aber bei gröÃeren Terrarien kann es schnell ins Geld gehen. Trotzdem: Die Qualität ist gut und man bekommt ein sauberes, gebrauchsfertiges Produkt, das keine zusätzliche Vorbereitung benötigt.Insgesamt bin ich zufrieden â die HydroBalls tun, was sie sollen, und machen den Terrarienboden deutlich langlebiger und stabiler. Wer auf der Suche nach einer bewährten Lösung für die Drainageschicht ist, macht hier nichts falsch. Ein Punkt Abzug wegen des Preises, aber klare Kaufempfehlung für alle, die auf Nummer sicher gehen wollen.
