The filter came with a bunch of media for the first "run-through" (idk) until it needs cleaned. It came with a bio-wheel type of thing that removes little particle from the water. The new filter has already cleared all the tannins from the water, so it's super clear and looks soooo much better now. One of the tetras has already died, but everything else is going great.
Two of the three baby catfish are still alive, but one of them has just one eye. I would cull it, the friend who wanted them when they hatched doesn't mind it only having one eye. And it's my very first batch of fry, so I just can't kill it anyway. The mollies I got are too fast for me to get a good picture of them, but I promise to have one sooon.
