Is it supposed to look or get that way. Looks like there's hair algae starting to form all over? If the marimo is not a true brackish ball I would not keep it in there. As far as the amonia I would not worry about it. The opae are really hardy.Hi Vorteil, the marimo ball looks messy because i turn on the light for more than 10hrs causing algae to grow but im not sure if it is a true brackish ball. I have used this marimo ball since the start of my first tank this year march. Yeah this batch of shrimps had went through ammonia spike in the first tank so im not worried about this anymore.

Can you get biodigest where you live? That stuff is great for this type of situation.
