ID bacteria/algae?

[MsAmethyst]

Added a few snails and 3 hermits on Saturday. 1 hermit killed another. Down to 2. 1 of the snails was probably almost dead when he was put in because he never moved after putting in. Another moved around enough to half bury in the sand. Both Ceriths.

I have 3 other Ceriths doing fine and 3 nassarious doing great.

Starting yesterday I noticed some reddish tinted coloration starting on parts of my live rock. Not slimy at all. Today it's spread a lot. Also small patches of green that I'm not sure of the ID on.

Can I can an ID on the green stuff and is the red a bacteria/algae? If so they which kind.

Green algae is typically good to have there are some nuisance species as well but your pictures don't show a lot of algae of any kind..red algae if coralline is good, but it could be Cyanobacteria also which is what it looks like. All tanks have it at some point especially newer tanks..some common causes are over feeding, low flow and or lights on too long. Regular water changes and not over feeding usually keeps it in check. Make sure you have adequate flow also...if your tank is new as it matures this will go away.

I am not seeing cyanobacteria
It will typically start to form on the substrate where hydrogen sulfide begins to build up.

looks like corraline starting.

If what your seeing is hard to remove from the rocks then it's probably the start of Coralline algae. This comes in all kinds of different colors as long as conditions are right.

Here is a great tip for reducing the chances of algaes and bacteria from entering your tank.
Do NOT add any of the water from the bags of purchased livestock.
