Algae Help

[UteMan3431]

I'm trying to figure out what this algae is, I'm seeing it over the back of my tank and on some of the rock. I have 2 Current USA ligt bars running the spectrum you see in the images. My tank is about 1 year old and my fish and coral don't seem stressed. I water change 20% weekly. Feed once a day and reefroid once a week. Tank is 50gl with a 25gl refugium. any advice? I have a canary blenny, clown fish, 2 pajama Cardinal, a cl aner shrimp, and a peppermint shrimp.

Could be regular GHA. Red and green settings are pretty high and many reefers set them at 10% or lower to minimize algae growth. Also looks like a lot of spirobid worms which propagate in nutrient rich water - might want to check parameters using good quality kits and adjust accordingly to minimize algae growth and improve overall tank health. Also, may want to remove algae by hand/toothbrush or scraping/siphoning up.

Good luck
