Thank you everyone for your information. For the time being, I will keep them open. I am aware of the evaporation part. Thats not too much of a big deal for me. My main point was any effect on my CO2. Since there are not much, its not a big deal then.
At the moment, the tank has just some snails that found their way in my tank. When I do add some critters in it, I will give the glass top a more closer look.
