I purchased 2 used Vortechs about 3 months ago that at the time where about 2 months old. It took me a while to install them in my tank. They have been running good for about 2 weeks or so, but now they are not sticking together (falling apart). The glass is 1/2" thick. When I go to put them back together the wet side part is spinning and about 1 hour latter comes off. I tried to clean all the parts and even let it stay out of the tank for couple days, but the problem didn't go away. Is there anything I can do to fix this?
Thanks for your help.
