Well, I'm back from the store with my Flourish, Flourish Iron, Flourish Tabs, stump remover, No-Salt, and last but not least a Fleet enema. I have 1.5-2 watts/gal with flourescent lighting, and have the following plants on a 2-2.5" 80% Flourite/20% sand substrate: Amazon Sword, Crypt Wendtii, Crypt Lutea, Water Wisteria, Java Fern, Java Moss, Vallisnaria, Hornwort, Anubias Frazeri, and some Pygmy Chain Swords. I've been through the site, but never really have seen what dosages or frequencies people use with the above nutrients for a 55 gallon tank...eg...how do you mix and dose the Stump Remover, etc? I could really use your help! Thanks in advance...this is a great site with obviously knowledgeable aquarists.
