There's a reason I don't join FB groups and it's because the communities are nasty and absurdly close-minded with little to no willingness to partake in civil discussions. There was actually a thread discussing how suitable/unsuitable tanks are if you are interested. https://ball-pythons.net/forums/show...lly-unsuitable
As for your UTH, it shouldn't be turned off at night. Since you have it regulated by a thermostat your heat sources are to be running 24/7 to maintain stable temps.
