We just got back from vacation and what was just red on sand is now this?

thank you.

Yes. Not (quite) an emergency, but yes - it's cyano.

hey I won’t tell you what an emergency is to you but definitely feels like one to me.

Not a super helpful reply above... can you give us your water test results?

 

[reefnewb70]

Yes, absolutely I’ll be testing the water parameters this morning. We just woke up. We didn’t get in till 2 AM in the morning and saw the mess.
