HI first off dust your crix with calcium with d3 and i use that 6 days a week and on the 7th day i us a multi vitamin and for bedding i use newspaper easy to clean. Also you dont need to have the powersun on during the night and me and my wife leave the lights on for 13 to 14 hours during the summer unless we take them out side to get real sunlight (no point in having the light on when there not in there cage) and during the winters we leave the lights on for about 8 to 10 hours.
i hope that helps my wife and i keep over 30 beardies and all are healthy and eating great.
