Under that condition, each model holds its full rated volume at temperature. Teco does not publish a broader table of capacity at other ambient temperatures for this range — where the room runs hotter than 30°C for extended periods, or the tank carries a heavier lighting load than the rated 0.3–0.5 W\/L, expect the achievable pulldown to fall short of the full rated volume, and size up rather than run a unit at its ceiling.\u003c\/p\u003e\n\u003cp\u003eIndependent bench testing (not Teco's own figures) gives a feel for real-world pulldown: a TK500-class unit has been reported holding a 540L reef tank under 27.5°C in a 30°C+ Italian summer, with the help of an external fan on the unit — useful context, but a third-party result, not a manufacturer spec.\u003c\/p\u003e\n\u003ch3\u003eWhich one do I need?\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eBest for\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTK500\u003c\/td\u003e\n\u003ctd\u003eTanks up to 500L with a standard lighting and pump load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTK1000\u003c\/td\u003e\n\u003ctd\u003eTanks up to 1000L, or a smaller tank with a heavier-than-average heat load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTK2000\u003c\/td\u003e\n\u003ctd\u003eTanks up to 2000L, or systems (display plus sump) totalling that volume\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eSize up rather than down if your tank runs hot lighting, a large sump return, or sits in a room that regularly tops 30°C — the rated volumes assume the standard test condition above, not a worst-case Australian summer.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e fresh and saltwater aquariums, sumps and systems within the rated volume, plumbed in-line with a return or dedicated circulation pump.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e running with no water flow through the unit — all three models need the stated minimum flow rate to work safely and effectively; check your pump can supply it before buying.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSafety\u003c\/h3\u003e\n\u003cp\u003eMains-powered, 230-240V, 50Hz.
