Thank you Duncan, I thought there would be a simple explanation, either way, it worked and seemed a lot easier than filling the tank with water.
Filling the tank with water has been my preferred method when welding many tanks. The advantage is that whatever happens the tank will not jump up and bite you. Weighed down by water means that any explosion would have a much reduced effect.
