I have what I believe is an infestation of hydroid jellyfish all over my glass, which seems to be getting worse by the day.
I've tried to suck as much out as I can during water change, scrape them off and then replace filter media, but they will not disappear.
From what I read, these should just go by themselves but at what point do you take drastic action to get rid of them? I'm sort of worried if it carries on, they won't go
Picture is from the other day, but it's actually worse today.
