What kind of buckets are these? I'm assuming they are old salt buckets, but maybe they aren't? I use a couple of food safe 65 gallon barrels for my water, and even after a month the water still has 0ppm TDS. I don't even use lids on them, just drape towels over them to keep dust out. I over-think everything too, and I'm super anal about things like RO/DI water, so in my case I would find your current situation unacceptable for fear of what exactly is that 5-10ppm anyway?? For the average reefer, probably not an issue.
