How To Fix Acrylic To Glass

Thanks to all the wonderful people and advice on here I now have a plan for my tank.
My lights are ordered. So only one thing to do before I can start.
The original lights got condensation in the unit so am upgrading to led.
I am worried about condensation getting in the new unit so will address this before I set it up.
The only thing I can think of doing is getting a condensation tray but I don't have a lip around the tank. But it has a brace across the center that's curved at the edges.
If I buy some acrylic square rods how can I stick them around the tank.

They are not deep enough to allow the condensation tray to clear the lights.
Thank you for your reply. I will see if I can find any deeper 😊
