The first pic doesn't look like coraline to me at all. It's some sort of green algae. I had the same stuff. My green algae disapeared about a month or two ago. I use RODI water, and I have a phosban reactor. My tank is 5 months old, and is just starting to grow purple coraline on the overflows, etc. Actual coraline can take 8 months or more to establish.
What kind of power head are you using with the phosban reactor? I am looking at getting one myself.
