My filterless pond(with falls) is so dirty with all sorts of muck like geese poop, never ending algae which idk why it keeps multiplying when I have plenty of plants in it, garden dirt.. and I was inside there with my waders on cleaning up the muck and cutting back my plants yesterday for a good amount of time and although I’m not sure if that was the cause, today I got stomach issues. I didn’t feel any water go in my mouth but maybe a small droplet went in without me noticing? Anyone else ever had this unpleasant experience after going in/maintaining your ponds?
