Just ordered a gallon of Metricide 14. I went to check on my chichlid tank (all thats in there is some stubby vals and a dyeing sward. I did the initial dose about 4 days ago, but nothing since. OMG! Directly under where I poured in the excel on the right side of the sward are over a dozen new leafs! And they are all at least 4-6 inches long already! I'm sold! 3 strands of the valls have also grown about an inch. Very happy!
