I'm using Green Gain and while I was trimming my tank out this afternoon I noticed something that I'd never seen before. Normally the leaves that float around the top of the tank (yes i'm lazy) rot after awhile. Instead, they all had miniature planlets growing at the base of them not unlike a java fern does with roots and all. So does it work..I say it looks that way.
I noticed this on Bacopa, Limnophila, and Hygrophila leaves so it was not a coincidence.
