Environmental control questions

[deranged chipmunk]

A ducting system is not necessary. Although they can be helpful. And yes, a PC fan is fine. But you do not want a lot of air flow. Just a little bit. Too much air circulation and you risk drying the tank out.

Keep in mind, that we are talking about air circulation here, NOT ventilation. This is important to distinguish. You would just want to have air movement inside the tank. Not venting or bringing fresh air in.

I'm not following your second question. Would you mind elaborating please?
