That's good that you adjusted the basking lamp, did you go with a lower wattage? Not sure if I mentioned it but you can actually use a standard household bulb for the basking bulb, there's no need to spend extra $ on a reptile bulb as they both give off UVA (but not UVB of course.) Were you going to order the Repti-Sun online or try to find one at a pet store? Make sure it is the Rept-Sun 10.0 strip fluorescent, not a coil or compact and also not the Repti-GLO.
Also, cutting back on the calcium to 5 days a wk, one feeding a day and then dusting with vitamins the other 2 days, one feeding a day is a good practice to start too.
Did you turn off the other UVB? Any idea when you are going to get the new UVB and digital with probe? When you get the new thermometer, let us know so we can explain just how to get the best readings unless you'd like me to tell you now.
