I am looking for fast growing (nutrient using) planst for my 29 gallon Amazon tank. Right now I am fighting a BBA crisis and need something to help out compete with the BBA for nutrients. I have 36 watts T8 and am using EI methods, Flourish and Excel, but no CO2. The plant(s) has/have to be South American in origin. I have plenty of swordplants and val, and recently added Alternatheria renekii. Does anyone have any good suggestions?
