Resurrecting this thread since I've got several questions/rants that it'd be easier to just put them all in here.
Firstly, I got new hides from Reptile Basics and, they don't fit the way I expected them to. They only fit longways as the tank isn't wide enough, which means there would be barely any room in the enclosure left after they go in so I've left everything as is for now since the way the UTH is set up means the warm hide would only be somewhat over it.
Secondly, I looked in two hardware stores and two pet stores and could not find coconut husk for the life of me. Several YT videos I watched said you could just buy bags of the stuff at a home improvement store for a lot cheaper, apparently not. Guess I'll just have to order a bag of Reptichip online...
And finally, I did some measurements and I think I'll have to buy a new plastic tub altogether because the one that came with the subpar enclosure I got (which I've since managed to resell) is smaller than the 30 gallon he's already in. The tank's 36"x13"17" and the tub's 27"x16"x13" so he loses height (which he never really uses granted) and length for a mere few inches of width.
In short, what I think I'm gonna have to do is get bigger plastic tote, another, better thermometer/hydrometer (the Grovee brand looks good) and another pair of thermostats. Possibly a bigger UTH too.
