Cyano

Any ideas for shifting a small cyano outbreak my local lfs told me to remove my activated carbon I have in the sump as it feeds cyano is this correct I’m not sure

Incorrect, maybe change out the carbon but don’t remove. I can only assume you misunderstood their advice or they didn’t hear your question properly?

Then they are wrong, AC is not causing Cyano. Best solution is consistent manual removal with wc, turkey basting, flow and detritus removal. Avoid any chemical solution just better maintenance.

No one really knows exactly why cyano happens in our tanks, no one can give any one singular reason for it.

Great advice thanks.

Can running blue lights only for a few days help

Cyanos in nature are often blue/green (hence the name Cyanobacteria). In reef tanks, and in nature at greater depth, where the light spectrum contains less red and shifts towards blue, cyanos adapt by using more pigments that absorb this blue spectrum better (namely phycobilins). That's why they appear red/purple in reef tanks.

As you can see, they are already well adapted to a blue-heavy spectrum, so any decline you might observe will correspond to the overall reduced availability of photosynthetically usable radiation, which will apply to all organisms in your tank, including those that compete with the cyanos.

You can test it, but I wouldn't expect too much.

Great thank you decided to keep my lights as they are and manually remove it for now thanks for the great response it isn’t to bad just annoying
