things are going ok, emersed. As expected, the hairgrass will take some time to transition. The old growth is dying off and new growth coming in. The ludwigia is doing good.
but I have no patience, so I planted what I have in my 5G tank. Yes, enough to fill in a 75G!. And filled in the tank.
The new additions are rotala green, c. wendtii bronze or red, and dwarf chain sword.
I'm waiting for the plants to grow in and watch the chain sword since they'll take over the tank and kill off the dwarf hairgrass.
Also, I'm experimenting with putting the outtake low in the tank to give the plants plenty of CO2.
