Still not using the airstone...
The diatoms are loving the fluorescent lighting... they're pearling like crazy, assuming it's the actinic spectrum that does it. Is kind of fun watching the pearled diatoms catch rides to the water's surface where the bubbles are released... the diatoms and the sand grains raining back down to the ground.
The shrimp are doing well, too. Noted several fresh molts under their shared shelter this afternoon.
Seems the chaeto is growing. No pearling on it that I've noticed, though.
