Sorry if this has been addressed prior, I couldn't find the answer. This is my first hatch and I'm like a cat on a hot tin roof. My Brinsea incubator instructs me to add their disinfectant to the water in the reservoir of my incubator. Problem: No one carries this around me and my eggs will get here before I can order some on-line. Question: Is this really necessary and if so is there an alternitive? Thanks for the help!
