Green crystals of film on my live substrate

[lherndo]

I have a crushed coral bottom and I have this green stuff on a few parts of the tank, I even have some on a piece of dead rock I seeded on top of the CC with LR stacked on top.

My guess is you had some Bubble algae that burst into your tank. I have the same thing. I cleaned my glass and bought a emerald crab and put a poly filter in to catch as much as possible. My problem is going away pretty fast.
That is what it looks like to me in my oppinion.
good luck,
Ed

I never saw anything that looked...

like bubbles or the pictures of bubble algae I've been able to find on the net.

Will a Harlequin Tusk eat an Emerald Crab?

How old is your tank? Is it by a window?

its about 3 months old

it's in the kitchen 3 feet from a sliding door, but it has blinds.

Does this help? I was told by a friend today it is just corraline algae like what grows on the LR.

I saw the same kind of stuff on the bottom of the tanks at the local Petco the other day. I had never seen anything like it before. It looks like green cyanobacteria. Very strange stuff.

I would probable say NTS or sunlight. Did your tank actually cycle. What size, How much LR and DR. Live substrate?
I used to get some pretty grass green like that in my first sterile FO tank. Unless its just the pic your rock looks awful clean/dead.

that crap on your sand is definately green cyno, I cant really see anything on your rocks tho.

 

[cdeakle]

Yup, Cyano.

One of the many nuisance algaes that visit us from time to time. Especially in newer tanks.....

Yes the tank is young,

it's about 3 months old. The rock in the picture is dead rock that I added when I moved the tank. It has live rock on top of it. It has completely cycled, and I just recently added some fish so maybe that's what casued the outbreak.

Is this stuff bad, or just part of maturing the tank?

Is there anything I should do, or just vacuum it up when I do my next water change and leave the lights off some?
