It's not the brand, Reptisun, that causes an issue, it's the fact that you've got an extremely weak, compact
UVB bulb to begin with, and then it's on top of a mesh lid, blocking almost half of the
UVB light emitted by the already far too weak
UVB bulb. And it's most likely way too far away from him as well, but that's not even an issue, as no adequate
UVB light is getting to him anyway, that I 100% promise you. It matter not one bit what you feed him or how often you give him a Calcium supplement, or how long that compact Reptisun
UVB bulb is on, without adequate
UVB light he's just excreting it all out.
I highly, highly suggest you not take my word for it, or AHBD's word for it, or Tracie's word for it, or Knobby's word for it, as every senior member/moderator on this board will tell you the same thing, a 13 watt Reptisun 10.0 Compact
UVB bulb is totally inadequate for a Dragon to begin with, and having it on top of the mesh lid is ensuring your Dragon is getting pretty much no adequate
UVB light...Don't believe us, but rather do a search in the search box of this forum for "Reptisun compact
UVB bulb" and see the hundreds of posts of what this specific, exact
UVB bulb had resulted in with pretty much every single Beardie that has ever been under one long-term...Sometimes it takes longer than others for the severe Calcium Deficiency/MBD symptoms and signs to present themselves, but I cannot promise you 100% on much that I'm absolutely sure of anything, but this is one of those things that I can...You may not trust all of the senior members of this forum telling you this, even though we LITERALLY see owners that have used only this exact compact bulb over their Dragons realizing they have a serious issue EVERY SINGLE DAY ON THIS FORUM, no exaggeration at all, that's fine, but you absolutely need to search for yourself so that you can see the end-game of using this bulb. It's not fair to your Dragon. And I don't know you, I don't know your Dragon, I have no vested interest in forcing this issue with you at all, EXCEPT that I'm passionate about Dragons and their welfare, as all the senior members and moderators on this forum are, and I can tell you that it's extremely frustrating to hear you say "This is not going to change, it's fine, he's always been under this bulb, yes it's on top of the mesh and that won't change either, I have a cat, blah blah blah" when I can 100% guarantee you that your Dragon is going to become extremely ill and have permanent disabilities if you don't get him a proper, long, 10% UVB output or higher UVB tube and a fixture for it that has a reflector inside it that sits behind the bulb, and if you don't mount that UVB tube correctly and within the correct distance of your Dragon's basking spot based on exactly which UVB tube you buy, which should be at least a 10.0 T5 strength UVB tube...
I said my peace, that's all I can do. I don't like seeing people come back her in 6 months to a year because they didn't listen to advice that has been well-proven and accepted over and over and over again...That's what I don't think you realize, you seemingly have no idea how common Calcium Deficiency and MBD are with the 13 watt Reptisun 10.0 Compact UVB tube...Please search it on here to find out what I'm talking about, this exact topic/problems resulting from it pop up on this forum at least once or more EVERY DAY...
