Domain Lion 305/blackstone Daintree Green Ink - "fuzz" On Tip?

[mcshiny]

Long time lurker, first time poster: I recently bought a Domain Lion 305, and have filled it with the Blackstone Daintree Green - I love both pen and ink, but I've noticed that after being capped for a while there's a fuzz at the tip of the nib that looks almost like iron filings on a magnet - I think what's happening is that the ink has evaporated off the tip and left the pigment residue behind. This happens over a few hours. Any suggestions for what I can do so that I don't have to clean the pen every morning? Is the ink to "thin" for the pen?

My procrastination-driven browsing of old threads has led me to believe this is known as "nib crud" and won't harm my pen. I'll see myself out.

I could be mold, which would be bad news indeed, because you'll have to dump whatever ink remains in the bottle and cleaning the spores out of the pen is a chore. To be certain, leave the pen alone double the time you normally would; the mold will have time to look more plainly mold-like (you may even get a festive dome around the breather hole).
