Hi! May I ask what sized water bowls do you guys prefer for what sized tubs?
I use 3.5 inch diameter for 16 quart and also hatchling tubs (when I had hatchlings), and 6.5 inch diameter for 28 and 32 qt tubs. Sounds about right? Can't find any smaller than 3.5 inch but when I had hatchlings it made the humidity a little hard to control.
