I’m pretty sure these are Filamentous diatoms based on a post from ReefBum with a very similar picture. Tank is 3 months old, algae has been there about 6 weeks. I have scrubbed multiple times. I ordered a Salifert Silicate test kit that will hopefully let me see if my RODI water has lots of silicates in it. I’m really looking for recommendations on what to do. Scrub and wait it out, 3 day blackout, chemicals?
