Okay so to clarify I have 3 light fixtures… a “daylight” light, a basking light and a red light! I have removed the red light now so I have the other 2 still for the daytime
Your cage decor looks great ! I was trying to spot the little one in there, I'll have to have another look. So yes, unfortunately the coil type uvb is what you have and they are not effective in a big + tall tank, the uvb is too weak. You'll need to get the long tube uvb that Karrie mentioned. Either a Reptisun 10.0 t5 or Arcadia D3 12-14 %. I know that lighting is super confusing and sadly many pet stores sell weak uvb bulbs.
