Sounds good. Plants can be a problem, especially when they are not doing well. They can mess up the water just as easily as fish can. Figuring out how to grow them takes some time. I tend to think it is much easier just to put some seachem tabs in the substrate and grow some low light plants, then to worry about changing the substrate and getting more than about 1.5WPG. But I am easily contented.
In the mean time, it sounds like you are getting good advice about treating your fish on the other thread.
