Coral questions from a noob!

I'll start with this one.

No idea what it is or what's on the sand. It looks blood like...I KNOW y'all know what's up. Please help, coral geniuses! [emoji38]

The red stuff on the sand is most likely Cyanobacteria. The coral behind that red patch looks like a Birdsnest. (Seriatopora) The large colony of polyps to the right are Zoanthids and I'm not really sure about the coral on the left. It's some sort of sps coral though.

Is the Cyanobacteria good or bad? Anything I need to do?

It's definitely not a good thing, but if the tank is fairly new then this type of "algae" is pretty common.

Looks like cyano to me as well. It is a bacteria that feeds on both excess nutrients in the water and light. Since this tank was just moved recently you probably have stirred up some stuff from the sand bed. Make sure you have plenty of flow and check for nitrates and phosphates. Good tank maintenance can help with problems like these. Chemiclean in my experience works really well but will not solve the problem. If you ever use this product make sure you follow directions exactly and make sure to add the aeration as specified. What type of filtration doe this tank have?

No idea. I need to figure out exactly what all I have system wise. It's almost like reading a foreign language!

IMO strong flow & often water change will take care the cyano
