Bioscape and independent retailers both note that thorough washing keeps the stone's effect on pH to a minimum — it hasn't been confirmed as fully inert, so it's worth checking your own tank's KH, GH and pH before and after adding a large stack if you're running a soft-water setup.\u003c\/p\u003e\n\u003cp\u003eA dab of aquarium-safe silicone between stacked pieces turns a loose stack into a solid cave or ledge that holds up to digging fish and determined cichlids.\u003c\/p\u003e\n\u003ch3\u003eGoes well with\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAquarium-safe silicone\u003c\/strong\u003e — to bond stacked pieces into a permanent structure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFine, light-coloured gravel or sand\u003c\/strong\u003e — a contrasting substrate that shows the grey stone off.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBioscape driftwood\u003c\/strong\u003e — to mix hard and soft hardscape elements in the same layout.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eCovered against being not as described under Australian Consumer Law. As a natural product, the exact mix of pieces you receive will vary box to box in size, shape and shade of grey — that's expected, not a fault.

It isn't confirmed as fully inert, so bucket-test it first if you're running a soft-water tank.\u003c\/p\u003e\n\u003ch4\u003eCan I use it outside an aquarium?\u003c\/h4\u003e\n\u003cp\u003eYes — it's also sold for terrariums, paludariums and vivariums, including reptile and frog enclosures.\u003c\/p\u003e\n\u003ch4\u003eDo I need anything else to stack it securely?\u003c\/h4\u003e\n\u003cp\u003eCareful stacking alone will hold for most layouts. For a cave that needs to survive digging fish or cichlids, a dab of aquarium-safe silicone between pieces makes it permanent.\u003c\/p\u003e\n\u003ch4\u003eIs it suitable for a marine tank?\u003c\/h4\u003e\n\u003cp\u003eWe haven't been able to confirm it as marine safe, so we're not claiming it is.
