I think, after all, it may just be deposits. Thanks!

I've noticed that the aluminum base to my 1250 watt "Ice Chaser" by Farm
Innovators (which is identical to the Beckett "pond De-icer") is
corroding.
I do maintain .06 percent salt level, my compromise on the "How much
salt"
debate. This probably causes the corrosion. My question is- is this bad
for
the fish? Thanks in advance for your reply.

Are you talking about corrosion or mineral build up? My stock tank
deicer has a build up of minerals on the element. At the end of the
year I scrape it off with a knife and it is still working after a
year. Happy water gardening.
