When I started with plants I had to get information from my LFS too. Witch was mostly just telling me to spend more. At the time I was just impressed with there tanks. I had no idea they would give me bad info. I find this all too common. I have to give credit to the good LFSs though there are some really good ones. If I knew that then my experience with the hobby would have been less aggravating. Despite that I love keeping tanks especially planted ones.
