Here is a shot of the leak test. It looks OK so far. I do need to shim up the right side a bit it looks about 1/8" lower than the left.
I got a few plants into the tank last night. The dwarf
A. gramineus is really a great plant and perfect for a nano setup like this one. Sometimes
Acorus are a bit tricky and resist growing, but these plants are doing well and already have good root development inside of the planter cup.
Notice that the cup is filled to more than 1/2 full with hydroton. It seems this plant does better with a coarse-grained substrate. As is true for
Anubias plants, it is also important for the creeping rhizome to be
on top of the substrate. It will rot if buried down in the gravel.
