I have an off road camper and want to add iodine to the tank to sterilise the water that wont drain out of the tank when not in use. Does anyone have any ideas on amount I should use. There is tablets available but very expensive and I have been told to use iodine but not told how much to use has anyone any ideas

Chlorine is definitely the way to go.
Although you may have a dark tank to prevent growth, it's possible the water you put in is contaminated with bacteria (not algae).
It can be very tricky getting the right concentration though.
You want a free residual of around 0.5 mg/L. Household bleaches (domestos etc) have a concentration of around 5%, that equates to 50 000 mg/L. Gives you an idea of the dilution factor.
If it's only to keep the dregs clean when not in use like you say it can't hurt to add a bit more (one squirt)
