Brown algae identification

[Pulsing Xenia]

Tank is approximately 6months
No dosing
Running filter sock
Skimmer
Chaeto
live rock in sump
Light cycle is 7am to 5pm 3hr ramp
Cant seem to get this brown algae to stop or slow down.


Attached is my last parameter testing
And a few pics with white light on.

Any help would be great!

Looks like diatoms to me

Recommendations to help reduce it?

water changes and its just a new tank phase
you can use a skimmer if your not and maybe gfo will help
also lights seem to help these things grow
so also cut down on light usage for a few days

Forgot to mention, I do have gfo running. As well as a skimmer

try cutting down on how many hours your lights are on
lights fuel these things i had them for a long time
eventually they will go away

Does look a bit like diatoms. Also a bit like the precursor to corraline. Usually that’s more green.

You’re on rodi water?
