Cool!
Did not know that, always thought it was general rule of thumb being 1w per litre of water.
Going to try and remember that for future references.
I always go for a higher heater than necessary anyway, my 90 litre tank has a 300w heater!
So that would possibly mean, for you, two 300w heaters and if worst comes to worst and one breaks down, one 300w might be ok to keep tank temp at acceptable levels until you get another heater.
In actual fact, might be good idea to have one spare in your kit cupboard.
I keep a spare heater and a small internal U2 filter in cabinet just in case.
