I'm from NY but have been in PA all weekend and happened to notice some very healthy looking hornwort growing in the lake by my house. I too was thinking about taking some home. I would not put it directly in a tank. I was thinking of growing it out in a bucket and maybe treating it with some alum to get rid of snails and maybe some potassium permaganate as a friend of mine suggested. It looks fantastic but I am a little worried about parasites and other critters.
