Hey looking into starting a 55 gallon planted tank trying to find a good lighting setup really want hoodless tank so something like http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3733+9871&pcatid=9871 Will prob do liquid ferts and root tabs. May do a DYI CO2 injection in the future. And one last question think 3 bags of Seachem flourite to cover the bottom?
