So i am getting back into reptiles after a few years of being out of them, mostly large monitors, and other lizards. I set up the tank (yes i know i have read all your posts and most don't like tanks but it's what i have to start with and i will be upgrading very soon). The tank has a UTH on it and a seperate heat lamp up top, my temps when the light is on ar perfect 92-93 taken with a temp gun, ambient temp is 86-85 across the rest of the tank,humidity is 60%. The problem is when the lamps off the temps drop to 73 which is what the temp of the room it is in. Now normally i would put a separate lamp on it with an inferred night bulb and call it a day but it seems like alot of people are running a the ceramic heat bulb and two other lamps that just produce light and no heat. Which is the better way to go??? The top of the tank is a screen top with about 75% of it covered with plexiglass. The subtrate is repti bark about 1.5 inch thick. Question number two I'm looking at pvc tanks to house my future snakes I'm not a fan of visions ( had bad luck with them in the past) But i really like the AP tanks mostly the T8 with the divider but will that tank be big enough for two adult BP's with the divider in, I like this idea because I can remove the divider if i ever want to try breeding. Thanks in advance for the advice.
