I wonder if it is really related to higher PH.
That's what I think in addition to it being more stable.
After I posted the first part I thought about it some more and tried to think of what else might have changed in my normal routine and all I could think of was feeding more of those dry foods. I've also been feeding some thawed and rinsed Masago lately. Masago is the little flying fish eggs that you put in sushi. The orange coloring washes out when you rinse it.
