Some section or another of my tank is lighted 24/7 so during the summer
I run either 1 or 2 fans 24/7 depending on the ambient air temp.
Once we are in real summer 30 degrees C + then both fans stay on a for
months.

I forgot to add this as well but I plan to only run the fans when I
use the lights, probably more so when I use the regular daylight
lights, not the actinics. Is this what most people do?
