Sea Magic is an organic foliar feed in an easily dilutable form. This is why I asked, that and because I already have it. Has anyone out there used it, or thought of using it? I also asked because I saw threads on this forum regarding superthrive, which is a vitamin supplement that I also use. And while I'm at it, why can't I use Alaska Fish Fertilizer as long as its properly diluted? It seems less than open-minded to discount a product just because it isn't specifically marketed as a planted aquarium product. Also, "easy" is one thing. "Inexpensive" is what this is really about, and the products I'm asking about are far less expensive than the products I have purchased that are "aquarium-specific."
