yeah, the whole stagnant air thing... That is what held me back from foiling my top at first. Basicly, in this case, it is BS.

As you probably already know, Many ball keepers use tubs in racks... including myself. yes there are holes melted into the tubs... but bottom line, there is VERY LITTLE air flow. a tank with a huge CHE hole in the top (screened of course) provides MORE THEN ENOUGH air flow.

I understand your frustration. Problem is there are even plenty of books out there with mis information. Your best bet is to come to this forum and talk to lots of people. I have studied every resource available... and NONE of them compare to the combination of folks I have learned from on this site.
