Here is a link to an article with much of the information on growing aquatic plants that I have found here in the forum and then some, all in one document. I am particularly interested in what the plant guru's have to say about the substrate information in the article. Have you tried this or a similar formula? Do you agree or disagree with the approach? The article is quite lengthy, but an enjoyable, interesting read.
