White stuff on algae and rocks

bms270 · 05/28/2009, 09:20 PM

Hi
I am in the fourth week of cycling my 125G tank and my parameters are 0 except Nitrate which is at 10ppm now. recently I noticed some white stuff are sticking to my rocks and algae on the rocks and I have no idea what they are. have you guys experienced something like this?
here are the photos:

I don't see the white you're referring to, but maybe it's sponge (I am new around here), I had sponge come up and was wondering what in the world it was at first.
Pineapple looking thing?

Im referring to powdery white stuff that are stuck to the algae in the pictures. maybe I can edit my picture to show it better.

I believe that is dead corraline. In the last picture inbetween the nuisance algae is a sponge.

I also believe this is corraline. It is hard to tell from the pics though. When a rock is removed from a high calcium high light area the coralline will turn white and flake off. This is likely what you are experiencing. In the last picture there is definitely a sponge. If a sponge is emerging it is a good sign your tank is cycling well.
