Ok, messed up the bong mod a bit and it took me a minute to figure out a simple way to fix what I screwed up!

Once it dawned on me....it was like: well, yeah, DUH!

Too many holes and some that are just too big. Here's the fix:
Cut some pieces of pvc pipe of workable length and then split them:
Add some pvc glue to the pipe and DIY "Collars".....and attach collars:
Drill fewer and/or smaller holes:
Cut a few zip ties in order to get the terry cloth back up over the collars and then re-zip-tie:
Get everything set back up and check the functionality:
So I wound up with 3 rows of 4x 1/16" holes....12x 1/16" holes total...per tube.
Ok. I'm Happy now.
Edit: Amazing. Truly Amazing. The Bongs are virtually silent now. Almost zero water noise and the only sound left is the fans. At 13w or 8w....they are not very loud at all. Very Cool.
Outside ambient is ~83F. Out-building ambient is 95F. Res temp is 85F and HVC temp is 83.5F. I just turned on the car rad fans after having them off for 8hrs. Looking to see what effect that has on the out-building temps and all the others....
