How much Milton?

Well, you could go with the recommendation on the bottle or you could pour about 1/4 into the tank, fill it, let it stand then empty and flush through with fresh. Empty again having seen whether the standing water was a bit "miltony" -if it was, then use a bit less. - trial and error really. No doubt the scientists, chemists, doctors and dentists on here will rubbish my offering.
 
I found this http://water.epa.gov/drink/emerprep/emergencydisinfection.cfm

I think taking into account the size of a US teaspoon and a US gallon and the relative concentrations of domestic bleach and Milton it works out a little less than recommended by Milton.

Stick with the 2.5 cm³ per 5 litres recommended by Milton but dont be heavy handed with the Milton... or you'll have rotten tasting tea all season!

I use a poor man's version of Milton [forget the name] at ca. £1/litre bottle. Going by the label the litre would be just right for my water tank so that's what I do at fitting out time and then do a few rinses. Mind you, we carry drinking water in 5l. bottles - buy a few new ones in the Spring and refill them ashore during the season. The boat water is for washing, washing up etc.

Bleach? I always thought that Milton was just domestic bleach already diluted so much that you could not kill your baby with it, am I wrong?

You are wrong. It is not just diluted domestic bleach.

The concentration of hypochlorite is 2% compare with around 5% in domestic bleach. It also contains 16.5% salt.

Purification processes remove traces of heavy metals that can cause breakdown to toxic chlorate ... as in weed killer

It does not contain any of the additives in many domestic bleaches that you may not wish to ingest
 
I put 3 cap fulls of Milton into a 200ltr tank on my first fill up every month. I usually fill up 4 times a month. Been doing it for years with no problems. An inline filter will take the taste of Milton out of the water and make a lovely tasting cup of tea for a bonus.
 
I'd say about one book of paradise lost per 100l of tank capacity to achieve purity followed by a little samson agonistes as necessary throughout the season
 
Ships Captain Medical Guide, free on-line from MCA, gives amount hypochlorite per ton of water, for sterilizing (one off, and then need to flush) and the maintainance dose. But if you want to give your system a good clean and get rid of all the floaty bits then "line-cleaning fluid", used by publicans for the beer lines works a treat. We got a bottle from our local pub for one off clean but then got a big bottle, I think 5 litres, from local supplier for under £20 and that has done us for last few years.

Just to add, if it is good enough for beer it is perfect for my boat!
