Whatever manufacturer warranty applies sits in addition to your rights under the Australian Consumer Law, which are not limited by any manufacturer's warranty. Where goods are not of acceptable quality you are entitled to a repair, replacement or refund.\u003c\/p\u003e\n\u003cp\u003eAt 81 cm long this is an oversize, fragile glass item and is handled as a bulky freight item rather than a standard parcel. Inspect the tank for chips along the edges and corners before it is filled — a chipped edge on a rimless tank is a structural issue, not a cosmetic one.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003ch4\u003eDoes the Bioscape 120 Ultra Clear really hold 120 litres?\u003c\/h4\u003e\n\u003cp\u003eNo. The 120 is a model designation. Calculated from Bioscape's published 81 x 36 x 40 cm external size and 8 mm glass, the tank holds about 107 litres filled to the brim and about 102 litres filled to a normal level 2 cm below the rim. Once substrate and hardscape are in, treat around 100 litres as your working volume for dosing and stocking.\u003c\/p\u003e\n\u003ch4\u003eDoes it come with a lid, light, filter or heater?\u003c\/h4\u003e\n\u003cp\u003eNo. The Bioscape 120 Ultra Clear is supplied as a bare glass tank only. There is no lid or cover glass, no lighting, no filtration, no heater and no stand. Everything needed to run the tank is bought separately.\u003c\/p\u003e\n\u003ch4\u003eHow thick is the glass?\u003c\/h4\u003e\n\u003cp\u003e8 mm, in low-iron ultra clear glass, on all panels. The 110 also uses 8 mm; the 170, 180 and 300 step up to 10 mm and the 400 uses 15 mm.\u003c\/p\u003e\n\u003ch4\u003eCan I use it as a marine or reef tank?\u003c\/h4\u003e\n\u003cp\u003eYes. It is plain glass and silicone with no equipment, so nothing about the tank restricts it to freshwater. The limitation is that it is undrilled — if you want to run a sump you will need a hang-on overflow box or to have the tank drilled by a glass specialist before it is set up.\u003c\/p\u003e\n\u003ch4\u003eWhat size stand does it need?\u003c\/h4\u003e\n\u003cp\u003eThe base is 81 x 36 cm, so a 90 cm cabinet is the natural fit. The critical requirement is that the stand supports the entire base panel flat and continuously. Rimless tanks have no trim to spread the load to the corners, so a frame that only touches at the corners or around the perimeter is unsuitable.\u003c\/p\u003e\n\u003ch4\u003eHow heavy is it when full?\u003c\/h4\u003e\n\u003cp\u003eThe water alone comes to roughly 102 kg at a normal fill level, calculated at one kilogram per litre. Substrate, rock and the glass itself add to that. Bioscape does not publish an empty weight. Always position the tank on its final stand before filling it.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":55242265559331,"sku":"AA3046","price":279.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-120-ultra-clear-gla-46120678785315.webp?v=1790239778","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-120-ultra-clear-glass-aquarium-tank-81x36x40","provider":"Nicks AOT","version":"1.0","type":"link"}
