Hello,
Which
UVB light are you planning on switching to? The basking light you are using now
should be fine, as long as the basking temperatures are optimal for him.
How is he doing this evening? I am glad to hear you took the sand out so he wouldn't get
impacted again. It may take him several stools to boot out the impaction so you can add in
some canned pumpkin, or sugar free applesauce, or both mixed with a drop or two of olive or
coconut oil daily to help also.
Let us know how he is doing.
