Just completed the first clean of the system.
There was a little bit of algae in the res but when I opened the blocks there were no deposits at all That's with only distilled water and a silver coil after a year!
I ran some clean water with about a cup of concentrated peroxide for a day to scrub away any life forms. Otherwise it has been solid as a rock.
On a side note, draining is a pain!
