Algae ID and Fix

[TheFishTickler]

I need an ID for some algae or bacteria I have noticed in my tank.

One of them looks white and stringy. Some pieces appear to have a green color. I am worried about what it might be.

The other - green spots/circles on the back of the tank - appears to be coraline, but I'm not 100% sure.

If any of this is a problem or bad sign, how do I fix it?

The parameters of the tank are nothing out of the ordinary for me. I did just add two cleaner shrimp, one leather toadstool frag, and a RBTA.

Its a combo of algae, dust from sand and what is known as chrysophytes. Blow loose with a turkey baster, scrub with toothbrush or algae pad, siphon and clean filters. Increase water flow slightly, lower white light intensity and add 1ml of peroxide at night per 10 gallons for the nest 2 weeks

I got reading about dosing peroxide after you suggested. Watched a few videos from stores that recommended using food grade, 35 percent peroxide. Other people used 3 percent. What do you use?
