Amazing what you can learn here. Maybe I should've listened more to those school chemistry lessons.

I am a cheap skate and poor so a tip if anyone is interested i used aquarium gravel the amount depends on size of the tank shake untill yours arms fall of empty tank,and repeat untill all the crap is removed i managed to remove 90% of 20 year old rust.

Good thing about soda crystals is that it can be deposed of down the same drain as the washing machine as they are not harmful

4th fill of water and shaken like a regular Harlem Shake dancer

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/030420131184_zpseb843249.jpg

All water out and seems to be clean enough to do, ran a magnet around the inside to collect any loose lumps of rust, but nothing in there

Removed the remainder of the water with an oil drainer pump up sucker as it's impossible to shake out the last litre from these tanks, filled then with a gallon of diesel shook again and drained and then added a gallon of diesel to hopefully stop or slow the rust till I get then fitted.

The 8mm bar than I had used as an anode had eaten down to about 4mm in places, must be why they call it the sacrificial anode
