Hi, I was wondering if anyone has had this happen. I woke up this morning and when i went to clean my glass on one of my tanks i realized it was covered in tiny white bugs, their soooo small i cant get a picture but theirs thousands all over my glass and in my water?? My best comparison is that they look like afeds like what you find on garden plants but smaller and white. Any idea in what they are and how i should go about getting rid of em? I had some sps in that tank that stated getting holes in them and losing all polyp extension so i moved them to my bigger tank i resently set up and i noticed the same bug on my sps. But i only saw one and didnt think that it was a big deal. Soooo i imagine its just a matter of time before i have them all over my other tank also.
