It's low-tech right now. The plants in this tank plus some now ones will be going into a 60U which will be very high energy shortly. I just want to make sure they are healthy before I relocate them. I'm still pretty sure they are parva, they look bigger than they are, the tank is only 4g. Leaves just over an inch long after a year or so.
The new tank will have a boatload of pteropus, buce, and anubias, Piptospatha ridleyi, these Crypts, some pink flamingo crypt, Lilaeopsis mauritania, Alternanthera lilacina, H. diformis and pinnatifida, a full stand of mini R. macrandra, and more. I have CO2 and a UNS Titan for the lighting with a good canister filter. This is why I'm really interested in making sure I have my fertilisers down.
