I set up a 40 breeder and a 20 long frag tank in August 2016. Both tanks are intended to see how I can do maintaining as simple a setup as possible. HOB Aquaclear filters, basic powerheads for more flow and no skimmers. The 20L has a cheap chinese T5 fixture. The only spurge on the build is 2 Radion XR15 Pro G4 lights on the 40B. A build thread is here:

By November I had some GHA and brown Dinos? in the 40B and some stuff that looked like cyano in the 20L that I was having trouble dealing with. I decided to try dosing Vibrant 2X per week. I've made a couple of posts in this thread:

It's been a long process but the Dinos and GHA are pretty much gone. I've had green bubble algae crop up which is mostly gone now. I've had to clean the glass 2 or 3 times a week but that's better this week.
The purpose of this thread is to try to identify some cyano looking stuff that has cropped up in both tanks. I bought a microscope this week in hopes some of the fine people here of R2R can help me identify the algae and develop a plan to deal with it. I haven't lost any coral yet but some don't look very happy. I'm most concerned with an elegance coral which has not been open enough to feed for over a week. I believe the Vibrant process has stripped the water too clean for the elegance to be happy. I last dosed Vibrant on Sunday 1/1/17 and will probably hold off dosing again for a few more days to see if it will open up and feed.
The 40B has places of red and green algae mostly on the sand but a little of the red is stringing from the rocks. It seems to be slightly better this week than last. The 20L has black stuff EVERYWHERE. It's on the rocks, frag racks, frags and glass. It looks worse than ever this week.
I'm starting this process with an H2O2 test of each of the three algae mentioned above. Here is a pic of the start of the test:
This is after 12 hours:
This is after 24 hours:
If I've interpreted what I've read from @twillard and @jason2459 correctly I believe the 40B RED sample is most affected by the H2O2 and is cyanobacteria. The 40B GREEN sample isn't really affected at all. The 20L BLACK sample turned red after 24 hours but isn't as affected as the 40B RED sample.
Microscope pics of all three samples coming up. I'm very much a scope noob so the pics aren't the best but hopefully their good enough for an ID.
