I have only had my ball Mitch for a couple of months and I am already tired of spraying his 20gl screen topped tank down 4 or 5 times a day. I have decided to switch to a tub. I have already purchased everything I need, the only question I have is what should I do about air flow? If any of you have advice or pictures I would really appreciate it. I would like to add that these forums are a huge help, I wish I would have found this place before I got Mitch, it would have saved me a lot of time and money. Thanks a lot guys you are all a big help for a newbie like myself.
