Thanks I think I will leave the water out. It will only be till Sunday afternoon so they should be good. I am going to pick up two 30 tub rack systems from ARS in a few weeks and that will cure everything. Sadly it isn't the adults that spill their water. It's the Juvi's that love to topple the bowls over. I use deli cups with holes cut in the lids but they still find a way to spill them. I worry more about them sitting in damp tubs and risking RI or something else.
