Help - Struggling With Brown Algae

[ReefAir]

Hey all, I've had my tank running for around 7 months now & haven't been able to get rid of this brown algae, mostly on the sand bed & partly on the rocks. I have a few dead corals die due to algae growing on them including two scolys & one torch head. Some of my other corals like hammers aren't opening up fully either. I've tried increasing flow, changing lighting & increasing/reducing feeding. Nothing seems to work, would appreciate any help!

that's good to consider as an option because your invasion is very very light, not much work would be needed to curb it at this stage.
