What is this in my fuge?

[bucfan]

Found this white fur like stuff in mu fuge, mainly on the green gracillaria, what is it and what do I do?

There are some parts of it that look like a sponge to me. How old is the tank?

 

[bucfan]

Tank is 4 weeks old.

That looks like chaet, not green gracillaria. Do you dose kalk? Looks like precipitate to me.

Is the bottom of the tank painted white? What is the white stuff on the tank floor? Do you put salt directly into the sump? It also looks like chaeto to me. Still some of it looks like sponges. I would agree that it looks like some white debris has settled on the algae.

You guys are right it is chaeto. The stuff just popped up and it looks like whitish fur some of it in balls some not. Tanks been running 4 weeks since I upgraded from my 28g and everything else looks well. Only this issue in the fuge and I did not know if I should be concerned.

I do not dose kalk, but do dose part A/B.

I jut looked at the picture and realized that it is rotated. So the white stuff is your wall at least what I thought was paint or salt.

With new tanks weird stuff happens. I have not seen these before. Maybe someone will be able to chime in and say what it is.
