Just bought my tank today (sunday) put my heatmat under, put the thermostat in, put my sand in (the pet shop sold it me) thats coming out tomorrow. What i need to know is how long do i leave it before i buy my leo and can i put just normal lino on the bottom or does it have to be a special type. Sorry if all these questions have been asked a thousend times before but i am new to this. Thanks again Craig.
