Found similar things with my tank.
Glut killed off a lot of my plants, cant remember what they all where but will find out for you. Seems some plants just cant tolerate the stuff.
However the remaining plants are doing fantastically well with glut so have continued using it.
Would be handy to have a list of plants that do and don't do well with glut???
I also found it not very effective against bba, luckily I only have some bba on the wood in my tank so it dosen't bother me but even quadrupling the does had no effect on the bba, it sent my fish a bit wacky though.
