The nutrient thing has been discussed by better than me on the APD in times past. Profile (the material Schultz' is made from) has iron. If you want nutrient-rich substrate, you'll have to add nutrients, whether it be Profile, Eco-complete, Flourite, or whatever. The most useful substrate amendment I can think of would be something to add humic acid to make nutrients available in the substrate. That's why I have added peat or leonardite to Schultz' recently in my small tank. I've used Profile since I started a year ago and it works fine. After considering KL, I just don't need the aggravation. There's plenty of alternatives to play around with. I'm not saying you shouldn't do it, but I don't think I will. I just don't believe you will see any real difference in the way your plants will grow, but you will see a difference during maintenance.
