I have my BP and my Boa in 28 qt tubs. I have one of the 10-20G ZooMed UTH on my BP and a piece of flexwatt for a 20G tank on my Boa. They heat up the floor jsut fine, but my air temps are in the mid 70*s the last few days and im worried about side effects. Should i get bigger UTH/Heat tape? Can i just put a lamp over the tops of the tubs and raise the air heat?
