I pruned the Rotala indica and the stargrass, and traded it in to a LFS for credit. I bought some Ludwigia inclinata var. verticillata ("Cuba") and Limnophila hippuroides ("Gratiola").

The stargrass has really benefitted from adding the nitrates/phosphates/iron/potassium, growing leaves that are double in size from when I originally received it. It seems that the stargrass needs a lot of potassium (>30 ppm per week) in order to prevent black patches from appearing on the leaves.
