MVB: 150W
what brand? There are several having "issues" at the moment.
Bananas are very high in phosphorus. Careful of those.
You might want to bump up your basking temps a little. The ambient air is getting cooler in most states and when that occurs, we need to compensate slightly.
Other than that, i really can't find anything wrong with your set up.
If you're concerned, I'd go ahead with that fecal.
One question...........any reason you use a Repti Sun and a MVB?
UVB can be over exposed as well.
