Filled and running, the 250 weighs approximately 315 kg (695 lb) — over 200 L total volume, so check the floor structure with a builder before siting it, particularly on an upper storey, over a long unsupported span, or on anything other than a solid ground-floor slab.\u003c\/p\u003e\u003ch3\u003eGoes well with\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA return pump sized to the plumbing\u003c\/strong\u003e — the sump and overflow are engineered for a mid-size DC return; check hose and bulkhead size before buying.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA protein skimmer rated up to 250 L\u003c\/strong\u003e — the sump's skimmer chamber is pre-plumbed to accept one.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA pair of Red Sea ReefLED fixtures or a single wide-spread unit\u003c\/strong\u003e — to properly cover a 90 cm run.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRed Sea Coral Pro Salt or Reef Foundation\u003c\/strong\u003e — for your first fill and ongoing top-ups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA heater sized to 245 L of total system volume\u003c\/strong\u003e — against your room's typical ambient.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\u003cp\u003eRed Sea's manufacturer warranty on the Reefer G2+ tank and cabinet applies in addition to your rights under Australian Consumer Law, which are not affected by any manufacturer warranty term or exclusion. Register your system with Red Sea after purchase and keep your invoice as proof of purchase. As a large glass-and-cabinet system, the 250 ships on a pallet by oversize freight rather than standard parcel courier — check the freight estimate at checkout, and contact us before ordering if you need help arranging trade or elevator access.\u003c\/p\u003e\u003ch3\u003eCommon questions\u003c\/h3\u003e\u003ch4\u003eDoes the REEFER 250 G2+ come with a return pump?\u003c\/h4\u003e\u003cp\u003eNo. The tank, cabinet, sump and ReefATO+ top-off are included; a return pump, protein skimmer and lighting are sold separately and sized to your setup.\u003c\/p\u003e\u003ch4\u003eWill one light fixture cover the full 90 cm length?\u003c\/h4\u003e\u003cp\u003eA single fixture rated for around 90–100 cm coverage will usually reach edge to edge at typical mounting height, but many aquascapers run two smaller fixtures on the 250 for more even spread and easier shading control over reef and mid-tank zones separately.\u003c\/p\u003e\u003ch4\u003eDoes my floor need reinforcing for a 315 kg tank?\u003c\/h4\u003e\u003cp\u003eMost ground-floor slabs and well-supported timber floors handle it without extra work, but any system over 200 L total volume is worth checking with a builder first, especially upstairs or over a long unsupported span — get that confirmed before delivery, not after.\u003c\/p\u003e\u003ch4\u003eCan I run the 250 as a freshwater planted tank instead of a reef?\u003c\/h4\u003e\u003cp\u003eYes — the tank, cabinet and sump work equally well in freshwater.
