Titanium heaters: Aqua One models supplied with controllers, plus Schego PTC heating tubes that require a separate external thermostat. External inline heaters: Aquael Flow Heater and Hydor ETH models for compatible plumbing setups. Check hose size, installation orientation and flow requirements before buying. Controllers and accessories: Aqua Medic T controller twin 2.0, Aquael Thermometer Link, heater covers and suction cups. The Thermometer Link monitors temperature; it is not a heater. Choosing a fish tank heater Match the heater to your aquarium volume, livestock's temperature requirements, room temperature and the manufacturer's sizing guidance. Wattage alone does not establish suitability: compare heater length, temperature range, installation requirements and freshwater or marine compatibility. Electronic control does not necessarily mean a digital display or Wi-Fi connection. Check whether a thermostat is built in or supplied separately. Schego PTC heating tubes must be used with an appropriate external thermostat. For Oase filter integration, verify the exact filter model and any required adaptor. Choose covers and replacement suction cups by their listed compatibility rather than assuming a universal fit. Foll
