I honestly don't think it has anything to do with your ph. Oscars in my experience have never been that picky about ph.
I would still suggest water changes before I started putting salt in the water. Before I started putting ANYthing in that water. LOTS and lots of water changes with Stress Coat. Like every day. It's a 100 gallon tank, you shouldn't fear doing 10% per day.
Have you tried wiggling a pice of fresh beef heart in her direction? Did you try live foods yet? A goldfish? A guppy? Something like that to peak her interest.
But the water would have gone from 6ish to 8ish in about a couple hours or less. Oscars can tollorate that?
Also, this is the tank she has always been in, I sadly have nowhere else to put her.
ger87410: We haven't been doing water changes, because the pH of our tapwater is so high, and we have no safe way to get it down aside from pH down. And we don't want the pH up again.
Remember this happend the day we did the last water change.
Today is day 8, She seems more generally paler before I think. pH is 7.2ish, no nitrites and such.
She isn't moving as much as before, and she now has a whitish oval shaped thing on her fin, my friend things it may be fungus or something, that or an damaged scale.
You have to look carefully to see it, it's on the bottem rightish of her caudal fin
EDIT: Oh, and yes I put some live food in, so far she hasn't really touched it.
Also, her eyes (both of them) look slightly cloudy, not like cloudy eye which I have seen on very sick fish, but more slight cloudness ontop of the eye. I have been told this can be caused by alkaline burn.
It's not very noticable, been there for several days, and you have to look close to even know it's there.
EDIT: I also forgot to tell you, our new siphon sucked up too much water on the last change. Not too much, but a little more then it should of.
