I've had the 500x for a while and it gets regular use, but only recently have I been permasoaking it, along with a few others. When I went to change the water today, I found a nice rainbow under that particular stone.
I also ran into some internal flaws recently consisting of little 'rocks' imbedded in the matrix. Easy enough to pick out, but still annoying. Anyone else run into weird stone stuff?
