I just got two pf these filters in a recent purchase, and I have no Idea how to open them up! I know this is probably the dumbest post ever but any help would be appreciated. I have never had an eheim before. There are all these metal tabs around the top, I unlock them and try to pull it apart but it doen't move. I am not sure if I am missing some kinda secret button or something!
Thanks for the help!
