    Hi everyone

    I was just wondering if a 50 watt heater would be too powerful for a 5 gallon / 20 litre tank? Could there be any problems?

    Thanks

    50 watt is a lot for a 5 gallon tank, a 25 watt would be better suited. I suppose if you have a decent 50 watt heater with a good internal thermostat it would be ok but I would still shoot for a 25 watt. For small nano tanks I use Marina's 25 watt mini glass heater. Its nice and small but is still adjustable and works much better than those little black plastic heaters.
