What is this algae??

[Hallowhead]

It's reddish in color and it's been showing up all over my tank recently. Nothing new was added and my tank was treated for bryopsis not to long ago. Doesn't look like bryoposis .. so that's good

As I am sure you are aware. Pictures on a phone make the task of identifying things like the diverse world of algae nearly impossible. Based on age of tank and your description. I will take a stab at Cyanobacteria. Although technically not an algae it behave in a similar matter and requires the same basic things. Light and nutrition. With that said, While these organisms do well in the 665 to 680 nanometer (nm) wavelength range, they are quite active between the 560 and 620 nm range as well. Which should be on the out skirts of reef lighting if your heavily in the blue spectrum. So I would leans towards to much nutrients and try to reduce that and vacuum any detritus. Of course reducing your photo period is always a good start.

So feed less and less frequently ? Or?

And reduce photo period ? Being my lights

Yes yes and yes.

 

[Hallowhead]

Yes yes and yes.

So make my lights less intense? Less blue? I am a little confused.

Less intense less hours per day and if possible more blue

personally i got some algae out breaks on my tanks, what i did was run a 30% degree cycle for 30 days ramping back to original form and saw the most improvement so for me i degreed the power of the light about 10-15% and algae faded away within 3 days maybe? was all gone lately ive been getting this blood red slime which i can suck out with a siphon but its due to lack of water changes and such been watching the QT too much i would do a heavy water change 30-40% reduce your WHITE lights alittle that causes the most algae or in general drop it 30% see what happens add some Carbon or get a https://www.amazon.com/gp/product/B00BUFTTE2/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1 works good thatll bring it down once it does increase like 5% every 1-2 weeks find the sweet spot
