Hey, I’ve had a diatom outbreak recently but fixed it, it was all because of my water. But there were diatoms all over it and I haven’t been able to get them off even with picking them off I cannot get them. And I’m not sure what to do because it has not opened up in a while, I’ve never actually seen it open up. I also have Duncan’s that diatoms got into and can’t get them out even with a toothpick I tried but couldn’t get it out what should I do?
