Cutting Metal Tank

[Datsun]

I have a very large metal water tank in my loft. Today I used my reciprocating saw to cut the tank and after 30 minutes I had a blunt blade and cut about half of an inch into the tank.

Can someone give me some advice on what would be the best tool to use for the job. My reciprocating saw get through everything but it doesn't seem to be up to this job.

Thanks in advance.

It needs a better blade and it should still sail through. A tip is to keep the 'shoe' of the saw in contact with the tank to avoid excessive vibration.

Thanks for the reply. Any advice on the blade as I was using a blade for cutting through metal?

I use Bosch blades for metal in a jigsaw - goes through like cheese.
You could use an angle grinder with a 1mm slitting blade but there is a fire risk.
