I just have to say I love how well these root tabs work
. Here is a before and after of my 29 gallon high tech tank that was doing poorly before. Also, a picture of my rubin sword growth with some very deep red coloring compared to the old green leaves.
29 gallon FTS as of 2/23/13 (eco-complete substrate)
29 gallon as of today. The crypt. 'Florida Sunset' sends out at least two new leaves a week. Also, the ludwigia inclinata 'cuba' in the center was only half the tank height a week ago.
