Growing on Sandbed: Need some help with an I.D.

[Longnose Hawkfish]

Hello everyone I need a quick id on a substance on my sand bed. Thanks

Looks like it could be Cyanobacteria. Do you have a phosphate test kit? And how's your water flow?

 

[Longnose Hawkfish]

Yes I have a phosphate test kit and from my last test like .03 ppm. My flow is directed higher in the tank but it's strong up top and decent towards the bottom. I'll try lowering it a bit

 

[pskirby95]

Try lowering it, and possibly run some GFO's just to be safe. Maybe try feeding a little bit less?

Cyano

Ok cool. Thanks for the id. I will do a water change, run some GFO and put the powerheads and a better angle

I have the exact same thing in mine.
