I unscrew the top hardware on the Aspire nautilus tank Aspire Nautilus Tank , and couldn't unscrew it so I had to use a pliers and my old Nautilus and the glass broke. I've never unscrewed the top hardware before so I don't know if it ever did but I know it's supposed to. How do I prevent the top hardware from getting stuck like this in the future? (I've ordered two new Aspire Nautilus tanks already.)
