I've been trying to get chaeto to grow/benefit in my tank.
I tried it in the main tank, and it got funky(covered in brown-then dying)
I tried it in the sump, and it got funkier(just a detritus trap)
Now it is suspended in the main tank where it gets more flow...........starting to look funky again.

Anyone know why in a healthy tank, I can't get this stuff to work?
