Pretty positive that is what it is. Tank is coming up on the 1 year mark and this is my first time dealing with it in this tank. I've been manually removing it but it seems to come back after a couple of days. Only a couple of small patches so I hope I can keep it under control! I've only really dealt with it appearing in the sand bed so I just want to confirm before I do anything drastic to treat it.

Just what is it in that photo that you think is cyanobacteria?
I see what looks to me like brown fuzzy stuff around some of the corals and rocks. Is that what you are asking about? I have something like that and I don't think it's cyano.

Toward the center of the picture where you can see more of a red tint. I tried to get a better picture of it but its difficult with my crappy camera. I have been manually removing it. Any ideas? It siphons off fairly easily and there just a few patches of it on the rocks. In this picture you can see the red stringy bit. That's what I'm concerned about. Not sure what it is. Ignore the GHA I'm currently getting it under control after an outbreak over the last few weeks.

Two suggestions
1. keep doing the manual removal. It is a bacteria and in time it should use up whatever it is using for food (assuming you aren't adding something it uses like carbon dosing).
2. add more flow in the area. As you said, it's easily removed, and due to that ease, if you increase the flow, it's very possible it will not redevelop with the extra flow in that area.
Good luck!

Thanks for the info! I have been adding Reef Fuel for about a month. I suspect that might be the food source for it? I won't be adding anymore until this is gone. I added another powerhead in that area to increase flow. Will keep up with the manual removal.

Looks like hair algse on the rock.Toward the center of the picture where you can see more of a red tint. I tried to get a better picture of it but its difficult with my crappy camera.

I'm still dealing with cyano forming on the rocks and now there is a bit on the sand bed. I have done the test with 3% hydrogen peroxide to see if it was cyano and the test confirmed it. The cyano turned green and the water has a red tint to it. So now from what I understand the next step is dosing 3% hydrogen peroxide at 1ml per 8 gallons every 12 hours for 14 days. Is that correct?
Anyone have experience with this dosing? My main concern is my corals. I have 2 black widow anemones that I worry might be affected. Everything else is pretty hardy. I have a large frogspawn, gsp, some zoas/mushrooms and a green toadstool. I will remove the carbon and gfo for the treatment. Anything else I should know?

I'm also trying to figure out what could be feeding the cyano growth. My current paramters are
pH - 8.2
nitrates - 2 ppm
nitrite - 0
ammonia - <.02
phos - .20
alk - 8.0
calcium - 420
temp - 78F
Phosphates are a high and I recently upped my lighting intensity. Currently running gfo to get my phosphates down a bit. Could the phosphates be the issue? I'm only dosing BRS 2 part and feeding my fish. The funny thing is besides the cyano popping up all my corals are looking fantastic! I will be trying the peroxide treatment once the phosphates drop.

Day 14 of the hydrogen peroxide dosing. I have added 4ml every 12 hours for a full 2 weeks and siphoning out what I can manually. I'm still seeing the cyano on the rocks although it seems to be spreading slower. I have done a 50% water change and cleaned my skimmer to make sure to keep the nutrient levels down.
Maybe I'm not adding enough H2O2? There is about 35 gallons in my system. I'm going to continue the treatment for now since it doesn't seem to be creating any issues in the tank. The water is super clear and the corals/fish are thriving. Just wondering if I should up the dosage?
