Ok, so the tank had some issues in the last month.... from a series of built up problems.
The problems:
1. hair algae all over back wall
2. Corraline die off
3. limited zoo growth and polyp extension
4. cyano bacteria
Diagnosis after trying to fix different issues for the last month
My PC lights were old, at about 7 or 8 months; replaced those that should deter nuisance algae with a better light spectrum
My calcium levels had slowly dropped down to about 360, so that is why my corraline algae had decrease, its die off was fueling the hair algae and also providing new landscape for the hair algae to grow.
Detritus accumulation; I did a full break down of the filter components and my Korallia. Used white vinegar to clean everything with a tooth brush; then dipped in two different salt water baths to remove the vinegar. Also used a wire brush to clean in and out for the pump components. (I hadn't ever done this in the 8 months that the tank has been set up)
Finally I scrapped everything off the back wall of the tank including white corraline growth and the hair algage.
Oh yeah, then a 3 gallon water change.
Now I'm going to replace the filter pad once all the debris settles to ensure bulk particulate removal.....
Here's a new picture; hopefully everything settles down!
