Hello, today I saw my turtle's poop floating on top of the water. Is this normal?? Personally, I have never had this issue before. My filter isn't able to absorb it either, which makes it a big problem to me now because oh my do they stink ? (don't worry, I changed the water already, but the smell is still there though. I think I will have to clean the whole tank next morning). If you're wondering how it looks like, it's like little clear particles floating on top. What should I do? Thank you in advance.
