A lot of good with the looks of those... I mean, I can barely see my bumblebee gobies with glasses.
But looks just suddenly hit me, when I took a pic of the tank with the dimmer morning/evening light on. It is just a single T8, 6400 K. And it looks so much better than the 3000 K HQIs produce. I was going to upgrade and now I see it's severely overdue.
Black mangrove is growing promisingly, I think. Survives pruning and all.
