How many vents for a 10 gallon?

[gmrpnk21]

Hello all! I am making a lids for my ten gallon aquariums, and I'm not sure how many 2" vents I should use. I want good ventilation, but I also want to keep humidity up

I'd say 3 to 5? Up to you really

Two on the top, one on the right and one on the left.

Lol, as in drill into the glass aquarium? If I were making the entire thing out of acrylic that would be easy!

Unless you work for a glass company, drilling it is a pointless and frustrating endeavour. The amount of airflow is going to be dictated by the species living within.

Then just use two on the top.
