At one of my LFSs today I saw a plant that they were calling Ambulia. It looks from the photos online that it was Limnophila aquatica. I thought it was a really nice looking plant and am interested in finding out if my setup has the right conditions to grow it.
I have a ten-gallon aquarium being lit by a 54-watt 6400k 48" T5HO, which is suspended roughly 16" from the water's surface and 27" from the substrate. I use a Fluval CO2-20, which in my tank raises the CO2 concentration to roughly 20ppm at the peak. I fertilize KNO3, KH2PO4, MgSO4, and Plantex CSM+B. I use Eco-Complete for substrate and sometimes use Seachem Flourish root tabs.
KH is roughly 3 or 4, GH around 9. pH varies with the CO2 level. No ammonia or nitrate.
