Did I drill enough air holes for air flow?

Hi folks!

We just built a new 40g crabitat and this is my first time switching from a screened top (half covered in saran wrap for humidity) to a glass canopy.

Humidity won't be a problem now, but are the holes I drilled along the plastic part of the canopy top enough to allow appropriate airflow? As of this moment, those drilled holes are the only air source I have, but I could prop open the split canopy top lid if needed.

Thanks in advance!

That's more than fine! When I switched from a mesh lid to a hinged glass one with a plastic strip at the back, I just cut out two small squares in the corners of the plastic to feed in the airstone tubing and assume that those apertures provide sufficient circulation.

Thanks so much for the reply!

Oh, and with added airstone it should be fine. The airstones would have to force in air into the tank which would be pushed out the top.
