Any updates, OP? Did the airstone help?

Yep, tannins can sketch out Discus. Did you boil that wood first? Also, what's your water change schedule?

I'm with the consensus - Duncan and frogspawn/torch do great in high flow, just as long as it's not blasting them directly.

I think I've come across people using these tanks for marine setups, but then again, could be something similar that's thrown me off.

"Could be your lighting's changed or maybe the bulbs are due for a swap. I've noticed with my own corals that when the bulbs start getting old, they tend to lose some of their color. Worth checking into, maybe?"

That background is seriously awesome.
