Trent, would you think the concentration would be similar. Is there any ratio listed on fertilizer to compare "strengths" of water soluable fertilizer? If it is about the same then it sounds like I wouldn't hurt a 2500sqft pond with that 1 pound box. Will it kill any fish or put chemicals in the meat? I live in Richardson and work in Plano so that's not too far. I'd love to come see what you guys have some time.
