Did you add the water during incubation or do you mean during lockdown? Did you only fill the 1 well once, or kept it full the whole time?
During incubation, I kept water in the one well..the whole time. During lock down, I had to add a lot of water to get it up to where I wanted it. All the wells filled, plus a couple of sponges..this was with the still air Little Giant. Around 62.
