Micro bubbles + White crustaceans On Back Chamber

[Harry g]

Hello everyone,

I’ve noticed these small bubbles everywhere, places like my sand and all over the rocks, the rocks in the tank are about 5 months old, but the sandbed is only about 3 weeks old since I recently moved, it’s caribsea live sand, if that helps, I’m wondering what these bubbles are, and if I have a problem and I’m also a bit dazzled on the white crustacean looking things on the back.

Thanks in advance:

I think so, I had already been told by google it was likely, any thoughts on the bubbles? Thanks.

Aw missed that.

It's either the beginning of cyanobacteria or unfortunately Dino.
Have you tested nitrate and phosphates?

It looks like you have Dino’s.

Phosphates were at 0.02 last week, I don’t think they’ve gone done since, I’ve been feeding flakes and overfeeding frozen to get nutrients up, I’m going to do a phosphate and alk test this weekend, they do go away after a bit if that helps. I have seen my return nozzle shoot some micro bubbles out and I’m also wondering if it’s a surface agitation issue?
