thanks all. i really do enjoy the anubias flowers also. they tend to put out one every month or so, and the flowers last quite long, too, especially emerged.
as for fertilization, my regiment is pretty simple and i try to keep it consistent in a weekly basis: 5ml flourish, 1/4tsp K2SO4, 1/4tsp KNO3, 2tsp epson salt, weekly water changes at 75F. no CO2 in this tank; i pulled it off after 4 months to keep it low maintenance... my tiger lotus was growing fast and too tall with the gas.
plants: anubias nana, java ferns, java moss, tiger lotus, marselia quadrifolia, a weird bulb plant from petsmart, and a giant common house vine. the water surface supports a bit of duckweed and a sort of floating pond plant which i forget it's name at this time. both are very prolific surface-growers.
