fishtanktv.com-So I took a bunch of the star grass out of my 220 in the basement and added it to the back pond. That is the only thing I can figure where these babies came from. None the less, I am excited. This is actually the 3rd year in a row that I've had baby rainbows back here, but this time when I bring them in I will only use water from the pond and SLOWLY raise the KH with tap water.....excited!
