Dust with CA/D3 2X and vitamins 1x weekly on different days with skip day in between. I prefer Repashy supplements but Rep-Cal is good too.
Zoo Meds Mini heat pad (RH-7) can be affixed to the side of a plastic enclosure. Another option is to use a desk lamp with an infra red bulb (do not exceed the lamp's max wattage). Then you adjust the distance from bulb to enclosure until you dial down the required temps. Good luck
