I have had my planted tank with amazon sword, hygrophilia, wistiria and java fern set up for 2 months with no problems. About 2 weeks ago i bought a ludwigia repens and it started to rot starting at it's base. I also bought a lilaeopsis novae-zelandiae and in the last few days it has been starting to really thin out. I am currently using 100w of standard lighting (looking to upgrade), pmdd fertilization and plain gravel. Anybody have any suggestions? Thanks in advance.
