I am new to this as I am building my station I'm learning.
So that was a question I had from the beginning: Why do I need to spray water around, doesn't the water cools off if I drip it out reducing the extraction power ? So your answer answers it.
So the main idea with sparging is to saturate the grains with hot water to push more sugar out of the crashed grains. So I don't really need an arm.
When do I start the sparging ? Do I do it while I am getting the wort out ?

If you want you can curl the tube around the inner wall of the MLT. I usually get 82% efficiency, and haven't noticed any channeling along the cooler wall. Just keep the water an inch or two above the grain bed.
