Shoot...thought I already posted a reply...hmmm :-?
Anyway, thanks Tanksman, excellent illustration. I tried it, but it didn't work. I thought it might because looking at my filter it is not level, so I played with different amounts of cardboard, but nothing worked! But I don't understand, why now it is so bad. Unless, the new stand, umm settled a bit :-? :-? I need to find my measuring tape!
What else can I do????
Thanks for all the help folks
