Ok so the DHG has spread across the bottom or vertically when you say six or seven times? Also how are the staurogyne repens doing after a month?Funny you should ask. I re-did my 29 gallon a month ago. Most of it is staurogyne repens. The tank was full when I planted it and it is spreading out wonderfully. I also saved a small portion of dwarf hair grass and some micro swords from before I changed it. I think I had 4 strands of each. The DHG is six or seven times that it started out as. And the swords probably take up around 3 square inches now.
