Ok I messed up my first tub by accidentally putting too many holes in it. And my probe for thermostat was in wrong place but Now i have all that corrected and bought a new tub to fix up! My Question is this cuz I get different response on here.....Should I put the starting air holes going in a line on all four sides or on just the one side which is the cool side?

Very IMPORTANT I get this info tonight cuz the tank I have my BP in isn't mines and the owner is getting their fish tank back tomorrow so I need to setup now so I can monitor and have her inside before I have to give tank up! Any help is appreciated!

Someone told me they put their holes on one end, the cool end, is why I am asking this cuz I put mines all the way around and my cool side wasn't cool enough and heated side was ok but I think if holes weren't there more heat could have been retained! So I wanted to make sure! Tell me what U think......
