As some suggest, lowering the light does help prevent/slow down GDA. On the other hand, how do we grow light-intensive plants? Specifically, I have HM (grows like weed), some HC, and as of recently glosso (it's a 375 L / cca 100 g tank). In my earlier (lower light) set-ups I never had GDA problems, however, now with lots of T5s, GDA is my biggest enemy.

And just to share with you, Alternathera R. seems to be a real magnet for this menace - Alternathera grows fast, but only the newest leaves are not plagued with GDA. I am at a point where I am considering kicking it out altogether. I am hoping that once GDA goes off the glass, it will also leave Alternathera alone.
