It is the deepest front-to-back tank in the Ultra Clear range relative to its length, which makes it the one to pick when you want to build a scape with real depth rather than a long, shallow panorama.

Spread over the 0.36 square metre footprint that is roughly 440 kg per square metre from the water on its own, before the glass, substrate, rock and cabinet are counted. That is a heavy point load for a domestic timber floor, particularly upstairs or in a Queenslander. Site it against a load-bearing wall and across the joists rather than along a single one, and get advice if you are in any doubt about the floor. Bioscape does not publish an empty weight for this model. Fill it in its final position, never before.\u003c\/p\u003e\n\u003ch4\u003eLighting reach\u003c\/h4\u003e\n\u003cp\u003eAt 50 cm tall this tank holds roughly 47 cm of water. Light falls off sharply with depth, so a budget clamp fixture that performs well on a 30 cm tank may not put usable light on the substrate here. If you intend to grow carpeting plants or keep light-demanding corals, choose the fixture on its output at depth rather than on its wattage.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Ultra Clear size do I need?\u003c\/h3\u003e\n\u003cp\u003eBioscape publishes six sizes in the Ultra Clear range.

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\u003eThis 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 170 Ultra Clear really hold 170 litres?\u003c\/h4\u003e\n\u003cp\u003eNot quite. Calculated from Bioscape's published 71 x 51 x 50 cm external size and 10 mm glass, the tank holds about 166 litres filled to the brim and about 159 litres at a normal level 2 cm below the rim. Once substrate and hardscape are in, treat around 155 litres as your working volume for dosing and stocking.\u003c\/p\u003e\n\u003ch4\u003eDoes it come with a lid, light, filter, heater or stand?\u003c\/h4\u003e\n\u003cp\u003eNo. The Bioscape 170 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\u003eWhat size cabinet does it need?\u003c\/h4\u003e\n\u003cp\u003eAt least 71 cm long and at least 51 cm deep, supporting the entire base panel flat and continuously. The depth is the catch — many aquarium cabinets are built 40 to 45 cm deep and this tank will overhang them at the back, which is not acceptable on a rimless tank.\u003c\/p\u003e\n\u003ch4\u003eHow heavy is it when full, and will my floor take it?\u003c\/h4\u003e\n\u003cp\u003eThe water alone comes to roughly 159 kg at a normal fill level, which is about 440 kg per square metre across the 71 x 51 cm footprint before glass, substrate and cabinet are added. That is significant for a domestic floor. Position it against a load-bearing wall, across the joists rather than along one, and seek advice if the room is upstairs or the floor is an older suspended timber one.\u003c\/p\u003e\n\u003ch4\u003eHow thick is the glass?\u003c\/h4\u003e\n\u003cp\u003e10 mm, in low-iron ultra clear glass. The smaller 110 and 120 use 8 mm, the 170, 180 and 300 all use 10 mm, and the 400 steps up to 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 Bioscape lists no drilled or overflow option for the Ultra Clear range, so running a sump means fitting a hang-on overflow box or having the tank drilled by a glass specialist before setup.\u003c\/p\u003e\n\u003ch4\u003eHow is the 170 different from the 120 and the 300?\u003c\/h4\u003e\n\u003cp\u003eThe 120 is longer but much shallower front to back, at 81 x 36 x 40 cm in 8 mm glass, which suits a panoramic layout. The 300 shares this tank's exact 51 x 50 cm cross-section and simply adds 50 cm of length. So the 170 is the compact way to get the deep, tall proportion, and the 300 is the same shape scaled up.\u003c\/p\u003e","brand":"Bioscape","offers":[{"title":"Default Title","offer_id":55293048291619,"sku":"ARI35","price":581.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/bioscape-170-ultra-clear-aqu-43179085496611.webp?v=1790233224","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/bioscape-170-ultra-clear-aquarium-71-x-51-x-50cm-10mm","provider":"Nicks AOT","version":"1.0","type":"link"}
