Co2 is set at 1bps, it's going through a small Ista reactor. But i've been meaning to increase it a little due to an increase in algae (gsa and bba). The light is 2x 24w, so the co2 demand is pretty high for approx 25L.
Ferts are 0.5ml ada step 2 and K each daily.
There's no UG in the tank. I think UG would look huge in this little tank (not that i've ever grown it). The stuff that looks like UG in the photo is rose moss tied to tiny rocks with nylon thread. The rest is all mini pellia tied to tiny rocks. In time the rose moss and mini pellia grown and attach themselves to the surrounding ohko/honeycomb rock and you can't even see the rock they're attached to.
I really really like this pic! Your scape is just amazing! Is there any chance you have a higher resolution of this or a new shot at the same angle? I'd love to use it as a desktop wallpaper / daily inspiration if you approve.
