Posible Cyano outbreak... Advice please!!!

[Gino]

Hello everyone, my tank it's been running for about 6 months. So far all parameters are on spot. My lights aren't the top end, even close, but they do their job. So far just diatoms and nothing serious, turkey baster and sucks replacement and that's all.

But today it's another story, well yesterday, but I didn't pay to much attention to it. Today it starts to cover the lighting section of the front in the sand bed. I didn't have adding softies and lps until last week.

I got a pretty decent stock on fish and I think that I reach what I want. Only left to add will be a sand shifting goby. My previous Diamond was a jumper. As I said, I took it slow with all the stocking to manage the bio load.

My question is how can I attack this possible outbreak before it's too late???
By the way it's a 90 gal with a 20gal sump, Miracle Mud, green grapes caulerpa, protein skimmer, UV.

Siphon the stuff out. Increase amount and frequency of water changes. Add some chaeto and or sea lettuce into the sump.

Hi, I got green grapes caulerpa in the refugium and it grow like weed... I will do a water change and a good syphoning. But I stir my sand bed on a weekly basis, because I like it white as snow. I think that I will do a 20gal plus water change. I'm trying to do a modified Triton method, no water change, but I'm not going to let this get out of control.
