What is it

Since the pictures are so bad I will describe it. I have two algaes growing on my sand one is powder brown and the other is black and looks like a spider web. I think it might be dino but i haven't seen any bubbles but I have only noticed it for 2 days. Also I have noticed a green strand like algae growing on my snails it looks like it is just single strands of green algae growing off the shell of the snail to about an inch in height. I have also noticed bubble algae growing on a rock so far I think it is contained to this rock should I bleach it? One more thing I think I may have Bryposis growing in my overflow I will post pics later.

 

How old is your tank? What's in it? Water chemistry and parameters are what? Someone trying to identify the algae may need some more info. Is your tank cycling or mini cycling for some reason, maybe that's causing algae bloom.

 

The tank is 6 monthes old. Found the problem Nitrate is 5-10ppm I have a fuge but I only got it a little while ago so growth has not taken off. I am also gonna reduce feedings and see if that helps. I still need the advice on the bubble algae and the stuff I thought was Broypsis is not it just hair algae. Still no ideas about the snails.

 

I have a bit of algae in the overflow and I just scrape it out and remove it manually when I notice it. There's a lot of flow and light where it grows. That's not too high on the nitrates if there is FOWLR. I found a couple small emerald crabs that eat bubble algae. I know reefcleaners.org have emeralds guaranteed to eat the bubble algae or your money back. The snails can get the HA growing on them, too. What do you have for a cleanup crew? Anything that cleans the sand? Also, do you have sufficient flow in tank? One last thing, could the black spiderweb stuff actually be dark burgundy-red cyano algae?

 

I would say it is more purple than dark red but also it seems to form little spires. I do have a couple corals.
