I got my tunze kit a couple weeks ago and today I had a problem with the magnet holder. The vertical cover on the sides of the mag holder popped off the inside piece while I was working in the tank cleaning things up. Not more than 20 minutes after the inside one had popped off, I was moving the tunze back into position and the outside one popped off! I couldn't believe it, but they just don't want to stick now, so I took a pic to show what I'm talking about. I got the whole kit 2x6000 + 7095 + 2 magnet holders from MD. Should I contact them or what should I do to get it fixed?
