how runny is too runny???

This is my first time breastfeeding, and although I assumed that her stools would be runny, they seem about the consistancy of water much of the time. I was doing an elimation diet for milk, and after two glorious weeks of a wonderful baby that hardly spit up and ate alright I had a glass of milk and WHAM! she has pooped at every feeding today and there are no “seeds” in it like i’d expect, but just yellowish liquid. It is so runny that it completly soaks into her cloth diaper and there is none “sitting” on top. Her stools are always runny, but not this runny.

So, the question here is “how runny is too runny?” I’m not sure if I could recognize diahera in a breastfed baby
