I just found this old thread. While the concentration of bleach mentioned looks way over the top, I am thinking of trying a drop of bleach or a bit of vinegar in the incubator water. I find that my fairly new incubator starts to smell towards the end of each hatch, and it seems to be the debris that has fallen in the water smelling bad. I really dislike the smell, and I'm convinced it can't be good for the last few late eggs as they hatch. I just did a quick water change tonight (end of day 22, but after 21 eggs hatching, very smelly). It made a big difference, but I would like to prevent that dodgy water smell from happening in the first place.
Does anyone have other suggestions?
ETA:
I'm just doing a general search for "incubator water", and I've found that some people add a stick of copper wire or tiny piece of copper pipe to the water to prevent fungi from growing in it - not that I think fungi is the problem, but I guess it could be. This wasn't a poultry site though.

Someone else says "To help prevent bacteria growth I use a bacteriostatic product that is made for room humidifiers and vaporizers. I add 4-5 drops to the incubator water bottle." I wonder what their product is. They are incubating cockatiels.

Google Book results won't let you copy their text, but some water additives for incubator water if you have known problems with micro-organisms in the water are mentioned here:

Aah, here is someone that puts "a little" bleach in the incubator water. Doesn't say how much.
