Hlle?

[Phanman]

I've been reading up on HLLE and cant seem to find any pics of this starting to happen besides the end result which seems to be holes near the face and body.

My powder blue tang has these flat semi white/transparent strips that are protruding around the face and side of its body. 2 have fallen off and he only has 3 more of these things showing.

There was stray current in the tank that i found yesturday so im going to get a GFCI and ground probe tonight. Im feeding mysis and pellets daily and upped the nori to every day as well to help him recover. I also do weekly 5g water changes on this 90g setup. Oh and going to grab some selcon as well tonight.

Sorry no pics atm and my camera phone really has crappy pics so not much use.

So is this the start of HLLE or some other diesease? and if so how do I treat
