Chaeto doesn't have ergosteral from what I understand. ergosteral is what makes bryopsis undesirable to be eaten by fish and invertebrates. That's why they won't touch it. As you see it turning white they will then start picking at it and eating it. The same for GHA. So yes it will mess up your scrubber. You can temporarily remove the screen and save it in a bucket of sw. But personally I would just clean it and restart it later.Not sure if my question been asked and answered. 194 pages already on this thread... wow
Anyway, What happens to other macro algae, like cheato and caulerpa.
If it blocks on bryopsis, why does it not block on Cheato?
It should destroy your algae scrubber as well. If effective on hairy algae, I do fully understand that. But why not cheato?
