Cyano or diatoms?

[CookieRdReef]

What do I have here? Brown cyano or diatoms? Tank is 9 mths old. I have near 0 nitrates and phosphates. I also have 4 young kids so I can't test this moment. Thoughts? Yes I use 0 TDS RODI.

Looks like diatoms cyano is red.

Thank you! I was hoping so. They also nearly go away at night. Is that a characteristic of diatoms too? I'm struggling to decipher the appearance of diatoms vs cyano vs dino. Appreciate the response!

Yes it does and cyano go away to when lights out. And dinos looks brown slim with bubbles in it.

Get those nutrients up.

 

[Jeff Jarry reef]

And bring your nitrates and phosphates at least detectable readings that will help too.

Thanks for the help! I will bring up the nutrients and maybe get a fighting conch if the LFS ever has one in stock.

Love my conch. The conch and diamond goby are the unsung hero’s of my reef.
