pond de-icer corrosion

I had one of those deicers coil eaten up by spring and there was no salt in the water
at all. and it had very high calcium (alkalinity) levels. Ingrid

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.
