This may sound kinda mean, but I just let Nature run its course. Some survive, most don't. Then I give away a few.
I don't have any pictures of my tank at work. It's a 0-anything tank... no ferts, no C02, nothing. I just have a lot of fish poop in there. I don't have spectacular growth, but nothing dies in there and the fish seem to be happy... and the Java Fern seems to do very well. I just took out a huge shrub of it a few weeks ago because it was getting too big.
I'll try to remember to bring my camera and take some pics tomorrow.
I have 2x 72-Gal bowfronts at home. One has Koi and large comets in it, the other is a planted tank with chubby goldfish in it. I think eventually when I finish the pond in the back yard, I'm going to move the Koi outside and convert the tank to a planted tank full of platys, mollys and such.
