Because it's described by the manufacturer as a non-toxic replica rather than confirmed as calcium-carbonate-free, if you're running a precisely dialled-in soft-water or blackwater tank — shrimp, for example — it's worth confirming the exact material with Bioscape before relying on it not to affect pH or hardness.\u003c\/p\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eRinse thoroughly with clean water before adding it to the tank.

Because this is listed as a non-toxic replica rather than confirmed shell material, we can't say for certain either way — if precise water chemistry matters for your setup, check with Bioscape directly before adding it.\u003c\/p\u003e\u003ch4\u003eIs it safe for shrimp and other invertebrates?\u003c\/h4\u003e\u003cp\u003eIt's listed as aquarium-safe for freshwater and marine tanks generally.
