In community aquariums with fish\/invertebrates from different regions, a water temperature of 24-26 °C has shown to be effective. 30 °C is only suitable for some fish breeding (e.g. discus fish). Many shrimp species come from cooler waters and do not tolerate temperatures of 25-30°C.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe water temperature should be set with an \"adjustable heater\" which regulates the temperature automatically. For this purpose, there are rod-shaped heaters which are fixed in the aquarium (JBL ProTemp s) in various wattages and external heaters\/in-line heaters which are integrated in the water-returning hose of an external filter (JBL ProTemp e) in two wattages.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe advantage of external heaters is that it is one less product to be placed INSIDE the aquarium and the distribution of heat in the aquarium is more even. In addition, the digital display of the external heater always clearly shows the current water temperature. The outdoor heaters can of course also be operated with a separate water pump.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eUndergravel heating is NOT used to set the water temperature. An undergravel heating cable ensures a better flow of water through the substrate of the aquarium, as the heated water at the heating cable rises and colder water flows into the areas between the heating cables. Thus nutrients are flushed to the plant roots and ensure optimal plant growth. Undergravel heating cables must always be supplemented by a \"main heater\" (JBL ProTemp s or e).\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpace-Saving Design:\u003c\/strong\u003e In-line heater integrated into the hose of the external filter, eliminating the need for an internal aquarium heater.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Installation:\u003c\/strong\u003e Cut the return hose from the external filter, insert the heater between the cut ends, plug it in, and set the desired temperature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEven Heating:\u003c\/strong\u003e Built into the filter circuit for consistent water temperature distribution, with +\/- 0.5 °C accuracy and 1.0 °C switching interval.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED Display:\u003c\/strong\u003e Shows both current and target temperature for easy monitoring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Hose Compatibility:\u003c\/strong\u003e Includes screw-on 3\/4\" hose connections for 12\/16, 16\/22, and 19\/25 mm hoses with secure hose locking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e Includes 1 in-line heater (300W) for aquariums of 90–300L (80–120 cm), multiple hose fittings, and a cleaning brush.
