Half Hatches

Do many people get half hatches consistently? I would say that most of the time my hatches come on 2 different days. About half the first day and the other half the second day. And there seems to be different survival rates. Sometimes the first hatch is hardier and sometimes it is the second hatch that has more success. I guess this is prematurity vs yolk sack depletion. When you get half hatches, do you use 2 different hatchery tanks? Or do you add the next days larva to the hatchery tank from the night before? I have always used 2 tanks, thinking that the first tank water would be slightly fouled already and a shock in parameters.
