Hello... Could someone give some advice on how to get my LILLAEOPSIS to grow. I have a 55 gal tank DIY CO2, 160 watts of flourescent lights. PH 6.5 TO 6.8 MEDIUM HARD WATER. All my other assorted plant are growing thickly but my LILLAEOPSIS hasn't done any thing but sit there the last 5-months that I've had them. Any help will be appreciated. Thank you Mike Bernardoni mikeb at pso_siu.edu
