Lots of GFO usage and they look great

I don't have tubs ( don't know what you mean ), but I've found the best results with my birdsnest that were brown was to reduce my tank's nutrients

Brown birdsnest usually means high nutrients ... HTH

Tubs birdnest is the one you are referring to as brown with purple polyp

Well I also thought that it might be because of high nutrient but previously I did some searching about birdnest placement and found they prefer low light for better coloration :S

So did some searching and found that the brown will turn green if placed in low-medium light. Makes sense since it was in medium/low light before my light upgrade and it was green. Maybe you can move it to lower light to see what happens?
