I started out using Florite, then mixed in some Ecocomplete. After awhile I got tired of my foreground not growing. I changed over to ADA Amazonia III. Had an ammonia spike for two weeks, daily water changes and now the plants are just loving the changes. I can grow anything I want in there now. HC, glosso, any of that. My choice, Amazonia if you want really nice plants. I don't even dose any ferts now (at least now). I have hard well water, so the minerals seem to do it well. My GH and KH went down to 4 from 11, the pH went down to 6.8 from7.2
