How big can a chaeto ball get?

[michika]

Mine kind of naturally maxes out at about something like that. I find that eventually a significant change either in its size, pruning, or a nose dive in water quality, will get it growing again.

I've never had mine max out, but I find it does better with lower flow. I always run refugiums around 100-200 gph...just trickling. The chaeto seems to prefer this too, and supposedly a slower flow helps the chaeto to absorb the nutrients from the water.

not sure what the max size is, but ive seen cheato the size of a fat full grown cat.

i used to throw out more then 1/2 a garbage bag of cheato every few months from my 125g sump in its hayday.
