Hey guys, so I just purchased a fan controller, a 40mm fan, and a power supply on amazon. It's set up and works well, but I have a few questions after having it run for the day.
First, the fan is on the lowest setting, yet the front glass (where the fan is pointed) is still clear. At first, that sentence reads weird, because the whole point of fans is to have clear glass (in addition to providing fresh air for certain plants). But I'm worried that this fan may be removing too much humidity. I don't have a hydrometer to test this, but it feels less humid than normal when I put my hand in. The fan is simply sucking new air from outside the tank and pushing it in, and the old air is (most likely) exiting via the front slits (this is an exo terra tank). My question is, should I modify the setup so that it's just re-circulating air, rather than pulling in fresh air? I've seen this setup on a number of tanks and I can definitely pull it off, but I'd have to go buy some more PVC - not a big deal, though.
Second, instead of recirculation, should I just put the fan on a timer and have it run a few times a day at most?
Third, if I do the recirculation, will the front glass remain clear, or no?
Fourth, with recirculation, do I have to worry about the water from the air re-condensing in the PVC and dripping out?
