What is this Red/Maroon stuff on sand bed?

[pinocchio]

This red/maroon stuff keeps showing up everyday. I have tried removing it by hand, but it keeps coming back. My syphon isn’t strong enough to suck it out and it quickly breaks up into smaller pieces. It’s a very thin coating. Is is algae or bacteria? Would love to know how to remediate or prevent it.

Looks like cyano to me.

Anything in particular that could be causing it?

Cyano.what are your parameters?

List your parameters so we can help you.

Hi phos will give you cyano.

Hi phos will give you cyano.

Not necessarily... I've had high phos for years and no cyano.

Nitrate 13.6 ppm
Phos .04 ppm
Alk 9.5

Cyanno

Try waving your hand above it (inside your aquarium/hands in) it should roll up into a ball, pick it out...
I may be wrong camera pics highlight red... But it's just general algae, either hands in take it out manually or Syphon it out.
Cynao or other

The phosphate at 0.04ppm is too low to ensure it’s actually available and not the margin of error in the test kit.
I’d run .1ppm tested Hanna to ensure, it’s not zero.
Zero in either or both favor pest type stuff.

My personal experience is that cyan comes from low flow areas

What’s the best way to increase phos?

Your ph is a little low. Do you have good flow thru out the tank?

 

[pinocchio]

I do have good flow. I can try turning it up. I have 2 gyres on about 65g. They are on the back blowing forward. I did recently move all my rock around. Maybe I created dead zones.

How old is your tank?
