Heater Size

What wattage would you recommend for a 600 litre tank, to be kept at 75 - 78 degrees Fahrenheit? The ambient temperature where I live is 68 degrees Fahrenheit. However the lowest it has been was 29 degrees Fahrenheit. I was thinking of 2 x 250W and 1 x 300W. Will this be enough?

I would go 2x 300W 1 should be enough but then the second may be needed depending on length of tank also good for a back-up

A 600 watt total should be plenty as long as the ambient temperature is that close to your target temperature.

Thanks

I'll go with the two 300 and see how it goes, as it's coming up to winter here.
