Okay so Im making a lid to cover the top of my tank out of plexiglass but had a few questions for anyone with knowledge on having their tank fully covered. I have the pieces cut out and fitted so my lights and filter still fit but was curious if I should drill holes in the plexiglass so the heat doesnt get trapped from the LED lights as bad or will it be fine without being drilled? Also didnt know if it would effect aeration or not. Also will the condensation that builds up have any effect on my lighting as far as shimmer be more intenese and what not.
