Pure water advice please

Best do your windows and check, but the insides too otherwise they might still look dirty.
I reckon nobody could actually tell if it's 3 tds, surely the minimal salts wouldn't have a visual affect on the glass unless they got out a microscope

I done my conny 2days ago when my reading was 003 and it came out lovely so i think wers alright

You should be fine, I'm cleaning with 003 at the moment and will probably not change my resin until 005 tds reading.

Apparently the human eye can't see a spot caused by a tds of less than 60ppm.

I'm gonna do a project innit.
