I started my 10 gallon 4-5 months ago with pool filter sand, Petsmart ludwigia and valisneria. The val melted and was still trying to fight for life until I finally removed the struggling shred of what was left a couple weeks ago. My ludwigia doubled within the first month, then I cut each stem in half and replanted. It went dormant for a while, but just decided to explode with new growth this week and is nearing the top of the tank again.
A few weeks after the petsmart plants, I added broad-leaf water sprite, needle-leaf java, windelov java, pellia and christmas moss. Those are all doing well, though none are really root feeders. I have the java fern roots in the sand, just for a place to hold on.
From a local pond I added recently: an unknown ludwigia, bacopa, and a small aquatic grass. The ludwigia is growing ok, the bacopa pretty well, and the grass surprisingly well.
I just added some amazon sword and hygro, both of which are growing pretty well, despite my spixies finding them to be a wonderful meal.
I added small Jobe's fertilizer sticks a while ago, but I didn't notice a huge difference. No water column ferts and no CO2 (most of the components are ordered, should be here next week).
