I bought two mature anemone’s recently. One about a month ago and one about 4 days ago. I’m turning everything off in the living room and the wife goes wHat the heck is that?! And points at this stuff. We watched a little longer and the anemone was spewing hundreds of them out it seemed. They are in the water column, sand and my water went from crystal clear to gross in like an hour. Do I need to get up and test and or just go ahead and change the water?
