Back in the day when I had a bottle of developer such as Rodinal or HC-110 go down in volume I'd transfer what was in the original bottle to brown glass bottles. If they got below an inch or more I'd add some marbles to bring the solution back up to the top. Whether that was necessary or not I don't know but, it gave me a warm, fuzzy feeling anyway.
I have that same occurrence now with HC-110 with the developer in it's original container down about 3 inches and went looking for my marbles but couldn't locate them. Anyone done this before or do you think it's an exercise in futility?
