Haven't done this yet but did some research - does anyone add a tiny bit (<1/8 tsp) of salt to their horses outdoor water bucket to keep it from feezing longer?

Adding it to the water works too. I use electrolytes (basically flavoured salt) to keep the water buckets inside from freezing as fast
You don't add it to the water you put it in an old milk container with water then close it and put it in their water bucket. You have to use a lot of salt in the milk container
