Rex, do root tabs add any benefit for root feeders? My assumption (which appears to be incorrect) was that the root tabs contained macros as well as other things. Is water column fertilization enough for root feeders? Is there something else to put in the substrate to provide macros? I've read of people putting jobe's fertilizer sticks in their substrate, but this always seemed like an algae problem waiting to happen to me. What fertilizer regimin would you recommend for root feeders?
FYI, my tank has swords, vals, and tiger lotuses as root feeders.
