It's also not a true drainage layer on its own in a terrarium, since the fine grade packs tighter than a coarse gravel — use the Coarse 2-4mm or 3-5mm underneath if you specifically want open drainage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eRinse before use, even though it's triple washed — a few minutes under a hose or in a bucket clears any dust picked up in transit and stops the tank clouding on fill; fine grades hold a little more dust than coarse gravel, so give it slightly longer. Once it's in the tank, an occasional gravel vacuum during water changes is all it needs; it doesn't need replacing on any schedule.\u003c\/p\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eAny fault on arrival — a torn bag or contamination — is covered under your consumer guarantee rights under Australian Consumer Law.
