has anyone ever tried chaeto in their main tank? have you had success with it? how much does it take to be effecient in nutrient export? i just recieved a nice wad of chaeto that i purchased off ebay. i placed in the the main tank behind the live rock. i have my rock aquascaped so that it bows toward the front of the tank leaving a nice little open area in the back. i placed in there with some live rock rubble to make a small in tank fuge. is it true that herbivors wont munch on chaeto? i'm hoping this will benifit my tank until i can afford to set up a sump/fuge.
