This is interesting, the shop I buy it from says it's no rinse but it clearly states on the bottle that it's poisonous. :?

Would it be a poison that accumulates in your system?

Iodine is a naturally occurring mineral. Small amounts are needed for good health and some take supplements. However, large doses can cause harm. Children are especially sensitive to the effects of iodine.

Copper accumulates not sure about iodine.

I spare with 75c acid treated water, have a formula to work out how much extra to add so never add too much, top up after if needed; getting high efficiencies 80% +

I believe that relates to the concentrated product, not the working dilution.
It's used extensively in the dairy industry.

https://en.wikipedia.org/wiki/Iodophor :

"Based on a review of the available toxicology data, the [US EPA] has concluded that iodine and iodophor complexes are of very low toxicity by the oral, dermal, and inhalation routes of exposure."[3]

I tried sparging a few times when I first got the BM, but I used a refactometer to compare the before & after results and didn't see any noticeable difference compared to doing a full volume mash, so I don't bother with it any more.

I know this subject has been done to death on this and other sites,
but do you have to change your recipe/water quantities if sparge or no sparge?
I have tried no sparge once and ended up with a 3.5% beer.
I am still none the wiser as to what went wrong.

Nope.

When testing I didn't find any more than a couple couple of points difference, so not worth the effort.

I do see your thinking though - easier just to add a few more grains if you have specific numbers to hit.

I tend to sparge because one needs to decant in any case when filling the malt pipe and it's not much additional effort.

I have however found the difference to be about 3 points when doing no-sparge (e.g. 1.053 vs 1.050). So much of a muchness I.t.o how important the 3 points are and one adjusts (or not) the grain bill for a no-sparge.

I decant pre malt pipe filling the litres required to sparge into a large kettle that is temparature controlled. [Need to decant in order to be able to fill in malt]. This then just sits there keeping temperature at about 75C. Once I lift the malt pipe post mashing and while it drips, I pour the sparge water in gently, piercing the grains. Start boil at the same time, so don't really loose much time nor is it a real effort.

Why are you putting it in in the first place?

Need to when I add water chemicals, but you're right can add after filling malt pipe. As its not really an issue I have stuck with the habit :D

Yes indeed - treating the water. Sorry I forget about that step.
Something I am very lucky with, my water is brilliant for brewing.
