Red algae outbreak?

[Aparker2005]

Hey everyone. We've recently started to have a small outbreak of this red algae. Not sure exactly which it is. It comes off pretty easily if you scrub it off. Snails, shrimp, crabs aren't seeming to do anything with it.

Lights are the new Current USA R24 Reef leds. Lights do a ramp up at 9:30, up to 100% intensity on red, blue, greens, except whites which are on 35%. Ramp down begins at 8:30 pm to moonlights for an hour or so.

It's in both our tanks now, a 75 and 40. Flow is strong in both tanks. Parameters I need to check. I'm thinking our phosphate may still be high due to feedings (lots of pellets and frozen cubes).

Any idea what this is? I have some chemi clean coming due to one of our torches having bjd. Will that help this temporarily?

Thanks!

Cyano? Should be able to blow it off and suck it out if so.

Looks like cyanobacteria. Definitely check your nutrients. They may be elevated and cutting back on feedings will help

Cyano shows up for me when parameters change. Don't think it's as reliant on nitrate and phosphate as the others.
