[quote=Emily6;503431]Very interesting about the frog bit- I never thought of just removing the center. I was trimming the roots but mine grew and spread like crazy- this was a weekly chore. QUOTE]

Even NPTs require some maintentance. I wouldn't consider removing excess Frogbit (or Duckweed) a chore. The continuous input of nutrients via fishfood must be counterbalanced in some way. In my opinion, its much easier to remove those nutrients via pruning/thinning plants than water changes, tank cleaning, or watching algae overtake the tank.
