I was wondering if I could drill a hole in my intake and silicone my tubing from my diy co2?
I think that would work fine. Even a stiffer bottle like a Hawaiian Punch bottle comes to mind. As long as the negative pressure won't suck in the sides, it should work. As always, use a second bottle as a ghetto bubble counter (and to keep yeast crap out of your tank if the bottle ever gets knocked over), and a check valve.I have been thinking about this and I now no from experience that it is for sure pulling any gases out of the plastic bottle. Wouldn't a thick glass bottle work? The vacume would pull the co2 out but would the yeast be able to keep up?
