It was a bit mucky and smelly (Old syrup) but a good few rinses and a hard scrubadubdub soon sorted that out!
It's a 200L capacity so makes a perfect partner for my big stripper. I've just dug out a 28mm valve to fit at the base, but Mrs Moose just came out and got a look, she's not too happy about having a "Fat White Tank" in the garden, so I'm going to have to get creative to make it blend in somehow...
Any suggestions?
