Help. Lost 4 fish and counting..

[Koiguyjoe]

I had 4 gold fish losses in the last 2 days.. and 8in Goldie has some discoloration on the top of his head.. pH is a little higher than normal at 8 & everything else is OK as far as i can tell.. removed pond plants, used a pH neutralizer 7 and did a 20% water change.

First pic is of the white on his head.
Second pic is of fish when healthy..

Any feedback?!!?
