Mark, have a look here at zappys blog for all the info on water treatment, I have used him for years and the tablets are excellent for cleaning tanks and pipes, do mine twice a year and they are spotless.

Clear Vinegar is good at removing limescale Mark. Not sure how many rinses it will take to lose the smell/taste.

Thanks peeps, Do tend to use milton sterilizing fluid sometimes but doesn't seem to clear the small amount of limescale in the tank. I will get some zappy tabs.
