H2O Capillary Action from canopy 55gal Hagen tank

[Morty1]

** looking for a fix **
PROBLEM: water damage to the metal frame of tank bottom and table tank is on
DIAGNOSED ISSUE is: water travelling down the outside of the rear glass via capillary action between the glass and the back mylar background picture.

I have a 55gal Hagen freshwater setup with the original factory canopy. I have under gravel filter system as well as the Fluval C3 external filter. The under gravel unit is full length in the tank and has 3 uplift tubes - each 'powered' by an air stone. When the bubbles from the airstones burst at the surface of the water, they cause tiny droplets of water to hit, and accumulate on, the underside of the factory canopy. Gravity and/or Capillary Action cause that canopy water to travel to the top edge of the tank, and then seep down between the decorative mylar scenery to the outside base of the tank. More capillary action takes that moisture all the way around the bottom perimeter.

I'm looking for bright ideas on: how to modify the canopy (or top edge of the tank), of a canopy replacement recommendation. I'd prefer to not build a bulky wooden top.

What I would do is to use a piece of nylon screening or filter pad banded to the top of the UG tube's cap so that the bubbles burst lower in the tank. Another option is to cut the tubes a little lower making the distance between the water level and the lid is greater as well as use the screening or pad to reduce the splashing that's hitting the lid.
Hope this helps.
