A while ago I was bashed for using top cover glass plates on all my aquariums. It was said they block lots of light penetration (18%) if 3mm thick, that they get dirty and hence need regular cleaning, causes heat issues and who knows what else.
While most of that is true, there is one benefit of using those glass covers that outweighs all of the negatives mentioned above - by a far margin. That is why I am today truly happy I kept the cover glass on.
See, at 06:00 this morning I heard what sounded like a burglar breaking in my house through the living room window. A very loud shattering noise sounded through the house. After investigation, I found that the one cover plate of my Sfigoli Infinity light pendant's 400W SE MH shattered to a thousand pieces, and all landed on top of the aquarium's cover glass. Had that cover glass not been there, I'd have to find 1000 invisible pieces of glass all through my tank - an impossible task.
