    I had Dophin heaters as well. Last well for the price. Last one one night leaked water in past the set thingy. And I had it for many years.

    Fresh and salt water the same heaters. No difference.

    Jeager heaters are better, if they pack up, they stop working in the open position. Cheap heaters normally stop working in the close position, overheating the tank. That is why having a heater that is underpowered for your tank size is better, but 2 or 3 units then. If one fail and want to cook your fish, it is too small on its own to do it. OK, your tank will run hotter, but you should notice that the next time you feed your fish.

    The heat in degrees Celsius is the difference in room temperature and the temperature you want to keep your tank.

    So if you have a 100 l tank and the room temperature which your tank is in is 20degrees. Then a 75watt heater is sufficient to keep the temp at 25degrees.

    I am running my tank without the heater even being plugged in at the moment (in JHB) and it is running at 27.1 ~ 27.3 degrees Celcius during the day. During the night is drops to about 26.6 ~ 26.8 according to my digital thermometer. I am however going to employ an STC-1000 temp controller so that the heater I have available can work when it needs to when winter fully sets in.

    I also have a nano that without a heater is running at about 28+ degrees Celcius, which is a bit hot but I am not going to get a chiller for that since it is only a QT at the moment. The heat from the pump is keeping it hot.

    It really depends on the circumstances if you actually need a heater IMO.
