Is this dinoflagellate?

[ixTCxi]

Can anyone ID if this is dinoflagellate?

 

[lazibonez]

Yes

 

[marrone]

looks like it.

 

[ixTCxi]

That's not good.

 

[marrone]

It's something that you get with fairly new tanks, how old is the tank?

 

[ixTCxi]

6-7 months does that still considered fairly new.??
It does not have any bubbles formation.

If it does not have air bubbles it is NOT dino. It looks like regular diatoms to me and they are a sign of a new tank. You can vacuum the sand and siphon it out.

It will settle on its own. All new tanks get it.

Good luck.

Cyanobacteria, long strings and reddish, as in maroon. There may be some diatoms mixed in with them. Both common to new tanks.

Thanks, I really hope is just diatom or cyano. What worried me was those long strings.
