Well currently I just leave the door open to the sub basement, so it is getting some passive ventilation, with the rest of the house, that way.
The reason I was contemplating the outside air for the skimmer was to, 1.counter act supressed ph due to CO2 build-up in a new house and
2. to muffle...
My 'fish room' is a ventless, windowless sub-basement. I am contemplating a way to get fresh outside air to my Bullet 2 skimmer.
Do I need to be concerned with the outside temperatures?
TIA
