Correct placement of exhaust valve...
    #379301 - 08/26/01 02:12 PM (23 years, 7 months ago)

A question on venting gasses in a sealed environment. This would pertain  to any type of sealed terrarium  where an air pump is providing not only fresh air but also building up pressure in the sealed terrarium. At some point the pressure/air within the sealed environment will start looking for an exit. It will take the path of least resistance out, so placement of the exhaust/vent valve is not important in that respect. Placement MAY, however be very important in properly venting the CO2/O2 mix, versus mostly(?) CO2 (since CO2's heavyier and tends to sink). Do you feel just placing a regulated vent at the top is sufficient or would venting at the base of the sealed environment be more beneficial? Further, if you do place the vent low (which would be in proximity to the air pump/bubbler), wouldn't the fresh air most likely make a quick exit (path of least resistance) rather than properly mix with the old air in the sealed terrarium?  Thanks.

well, only an air pump (i assume an aquarium one right?) isn't enough to a complete air exchange unless the terrarium is very small.
For the exaust valve, this should be placed at the same level of the cropping surface. so the co2 goes out.

CLuB99, Thanks for the reply.

McMan, I'm using an aquarium style 'under gravel filter' technique (with an air pump) to lift and deposit water (from a reservoir) onto a suspended layer of geolite (via 3/4" PVC tubes) and provide fresh air into the terrarium. So the actual fresh air inlet will be approx. midway up the height of the terrarium. The cropping area is located on a plastic eggcrate shelf slightly above the geolite. So this terrarium is for casing style teks only, since the substrate never benefits from being able to draw water directly off the geolite.I can put the exhaust outlet wherever it needs to be. Thanks.
