Quick question about the oust fans. I understand why it is a good idea to use one. But what size humi is too small. I just got a new 200 ct with two top shelves and a three section bottom. The top was much more humid then the bottom. I removed the credos from the inside of the lid and it has since balanced out. Is this humi too small for one? I am thinking about using beads, is that a better solution for a humi this size? I do have a tube with crystals in the bottom that I use for my leather travel case and it keep the bottom nice and even. My other desktop is only a 75-100 count and with no shelves I never had this problem. Just wondering what has worked for others. Thanks in advance.
