Interesting comment, but if you dont know whats normal, how do recognize something thats broken?
So, I guess you need to set them up properly, see a period of time thats normal, then you will recognize when it is broken.
Try for yourself, the monitor will teach you best. Usually when newer keepers think everything is fine they get a rude awakening, but this takes time, its in their nature to appear healthy until they cant possibly take it anymore, most times its too late then.
Recently werent you having problems with your bosc? I dont remember exactly, I only visit this place infrequently now.
Dirt is dirt, coco-mulch is not dirt. If you look at the soil content of the parts of Africa where bosc and whitethroated monitors live you will see its very very low organic content, high in certain minerals, and very close to what you see in many places along river banks, you know the stuff many animals here in the US like to burrow into.
