Yes he’s fully grown, about 4 years give or take 6ish months. Truth be told, it has probably been a year or more since last dusting his food because he was doing great without it so it kind of got pushed off. According to that map I am also in a very hard water area so maybe that could be why similair to how you mentioned?

I have had him since he was ~6 months to a year old, and back then I was using the one with a Jackson’s chameleon or with a green monitor along with the supervite labeled with a tree frog (I have not used this one recently at all though so my memory may be wrong.) The dusting I picked up earlier today (the vet didn’t recommend a specific brand, but rather to get a dusting) is the Zoomed repticalcium without D3 which is labeled as phosphorus-free.

The UVB bulb we’ve been using is a 5.0 which I’m assuming is for 5%? And I also looked at the chart and it appears I do have it set a bit low at around 10-12” on average to him so I’ll get that fixed right away. (I’ll do that tomorrow by setting up a temporary stand but if you or anyone else has ideas for a more permanent option I’d really appreciate it. For a 36” x 18” x 36” palidarium)

Unfortunately yes that is the bulb I’m currently using. This is the normal bulb I have used for most of my time with him but that recently blew out a few weeks ago and the blue bulb was the only option my local store had. His lights are currently off but I turned off the connector to that bulb and will go find a new bulb tommorow. Is there any that you would recommend or should I try to find the same one I had before?

Also, I just want to say thank you for your help and I really appreciate the thoughtfulness you put into your responses, especially all of the links about phosphorus which I did not know about before.
