How do you have those power-head attached filters set up? I've only got one and right now I have it filled with two small mesh bags full of smaller ceramic media instead of the tiny plastic baskets it came with surrounded by a sheet of filter floss. I traded in some of the mech for about 5x the bio.
And do you have a main display tank elsewhere? If so, what's in it?
Other than that, beautiful stock. Nice work on the fish room. Your NGT is stunning!
