:oops: Aww thanks.
I have grown glosso in 30cm of water but it got covered it algae. I really want to try a dense hairgrass carpet again but the tank is being used for fry. If you look on some overseas forums, namely plantedtank.net's nano section you'll see this is what they use. That hairgrass tank waas ignored, just a couple of JBL fert balls at the start, play sand, that light and no CO2.
