what kinda substrate?

[Loki]

ive got a little nile an hes fast out-growing his tank so im planning on building a much bigger one which should last him a while(hopefully.........) anyway my monitor loves to dig, so i was wondering were i could find a substrate that will hold a burrow

If you go deep enough cypress mulch may hold a burrow.

Got any nice, clean river beds near you?

go outside, dig up a pale of dirt. put some water on it and pack it in. then use your hands to dig a burrow, if it holds there ya go... you have substrate capable of holding a good burrow.. good luck

i thought about that, but wat about mites?

mites are always a possibility, just get the dirt from an area thats relativly reptile free.. you wont find any mites, i never have
