I don't know about the O2 situation, but I think the pH swings sound like 
bad news. .4 pH units in a day is pretty hefty. The fish are clearly 
surviving, but I bet if the pH stabilized they'd be much happier and more 
long-lived.

If only I had the pearling 'problem' in my light-deprived 37g tank. ;)
