Allow the heater to sit submerged for 15 to 30 minutes before plugging it in so the quartz tube can adjust gradually to the water temperature. Once plugged in, set your target temperature on the external controller and verify accuracy with a separate aquarium thermometer for the first few days of operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I adjust the temperature without reaching into the tank?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. The external controller is specifically designed to sit along the cord outside the tank at all times, giving you full temperature adjustment and monitoring capability without any need to reach into the water or disturb the aquarium. Simply use the controller buttons to set your target temperature and read the LED display to confirm the current water temperature and heating status whenever needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich power option should I choose for my tank?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eChoose the 500W model for tanks holding up to approximately 300 litres, and the 1200W model for larger tanks up to 700 litres. Using a heater matched to your tank volume ensures efficient, reliable temperature maintenance without the heater running excessively to compensate for insufficient power in a large tank or cycling too rapidly in a smaller one. When in doubt, selecting the higher power option for your tank size provides a useful heating reserve during colder ambient room temperatures.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat safety precautions should I follow when using the CozieFinx heater?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAlways unplug the heater completely before placing your hands in the tank or removing the unit for any reason. Never allow the heater to run outside of water as operating the heating element without submersion will damage it immediately. Form a drip loop in the cord between the tank and the wall outlet to prevent water from running down into the plug socket, and connect the heater to a GFCI-protected outlet in the US or an RCD-protected outlet in the UK and EU for essential electrical safety during all times of operation.\u003c\/p\u003e","brand":"LusaMax","offers":[{"title":"500W \/ US","offer_id":48319844614315,"sku":"TL01146533 - US plug - 500W","price":218.0,"currency_code":"USD","in_stock":true},{"title":"500W \/ EU","offer_id":48319844647083,"sku":"TL01146533 - EU plug - 500W","price":218.0,"currency_code":"USD","in_stock":true},{"title":"1200W \/ US","offer_id":48319844679851,"sku":"TL01146533 - US plug - 1200W","price":238.0,"currency_code":"USD","in_stock":true},{"title":"1200W \/ EU","offer_id":48319844712619,"sku":"TL01146533 - EU plug - 1200W","price":238.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/1274\/9227\/files\/cozie-finx-img-17.jpg?v=1792465533","url":"https:\/\/www.lusamax.com\/products\/coziefinx","provider":"LusaMax","version":"1.0","type":"link"}
