Brown stuff in chamber

[Adam113]

So I have chaeto in a little plastic container in the rear chamber in my NUVO 10. It is under light from about 9PM to 7AM. Just recently I've noticed a brown tint on surfaces, including the plastic container, only in the chamber that the chaeto is in.

Does this chaeto look healthy? It's not brittle or anything. Nice and springy.

What could this brown be from? I have a bunch of sponges back there, but only the middle chamber has a bit of brown to them. Just trying to make sure it's nothing coming from the plastic.

Super simple. Little plastic container floats in the back, and every night I just bend my gooseneck back there.

What's up with the "clear" parts? Pods are exploding and all over tank. My YWG is loving life and is all over the glass.
