Oh yeah, So I can't edit my last post now...So another question is, does taking my screen top off, stress the snake? Like to for say 1.change the water and 2. get a proper temp read with the temp gun(It seems to try and take the screen temp instead of thee substrate). While I am also on this topic I do think think after this reptibark is done I will end up switching over to a mulch(from somewhere like home depot or lowes.) The only things I have seen/read was to watch out for 1.NO cedar or pine and 2. make sure its not chemically treated? I would also like to inquire on how to close up my tank on the outside? It is in a closet space so it should not feel too terribly open but my closet is rather large(enough for me to stand on either side of the tank and have room to move around)
