Chaeto tank size

[reefwars]

wont matter the size for cheato as it will get harvested weekly if it grows good. obviously the more you have the better job it does.

it also loves nitrates


i grow almost a basketball weekly:P

Since Chaeto does best if it is tumbling you need to either make a cube shape (matching depth of the water) to accommodate a ball, or make a long narrow section to accommodate a hotdog shaped wad of Chaeto. I would suggest when you design this that you consider that your reef should only need the Chaeto in the first year (or maybe down the road on occasion when you're having troubles with nutrients). It is a nice option to have.
