I should have known since Marimo balls are a type of clado algae. This could probably be the reason why I had clado growing everywhere in my tank.
So now, the clado ball is out of the tank and into a glass jar on the window sill in the kitchen. Hopefully this decreases the likelihood of clado outbreaks in the tank.
