The guide for heaters I work on is 1W per liter, so 76l means 76W is ideal. Ok, the 75W heater would have been 1W underpowered, but if it's indoors in a modern house kept at a comfortable temperature, that 75W heater would have been fine Over-heating with conventional heaters isn't advisable, as they can make the temperature bounce. Not an issue for healthy fish IME, but can be for ones that are struggling for what ever reason...
