Mushrooms and Ric not Opening

[Rocco8]

I have some brown mushrooms with a green edge and a pink yuma that aren't opening fully.

pH 8.3
Ammonia 0
nitrite 0
Nitrates 15
Calcium 440
Alk 10.5 dKH
Sg 1.024
Temp 80°F
Phosphate 0
Magnesium 1050

They used to open in their exact locations. I had a bad pH probe and added a buffer that spiked dKH to 17 this in turn killed many mushrooms. Now I rely on the pH kit again. Four water changes brought it back in line. These are the survivors.

Any thoughts?

Keep an eye on things. Nothing you can do. Lack of stability was the issue and yumas really hate swings of any kind. If the yuma will accept a little something to eat that would be a good sign that you will get by. Don't for the moment do any changing and just keep your parameters steady..
