Help with ID of this stuff

[bh750]

Hi all, rather than keep guessing and without having a good microscope I figure I really need to properly ID things before I treat. Novel idea, I know! :-)

Any ideas if this is Cyano or Dinos...or both?

Quick background I had been battling GHA and dosed Vibrant which quickly did the job. But then I had a bad outbreak of Cyano. I dosed H202 and it almost went away. also did tons of water changes. My NO3 is about 1ppm and Po4 is undetectable using a Hanna Low Range Checker.

Now onto the pics - I spent some time trying to take some high res pics. I have the bubbles on the glass, rocks and pumps. On the sand is brown stuff. A few strings. But mostly just brown.

Any ideas?

It looks like Dino's to me.
You can test for cyano by using 1 cup of tank water add some of the so called cyano/Dino's to it dose 3ml of hydro peroxide to it
Swirl it slowly and if it change color we talking cyano.
If it doesn't it's spirulina.
Maybe @twilliard can chime in for Dino's.

I'm dealing with the same stuff in my tank after using vibrant.

Thanks. I remember that that cyano test from @twilliard. And there's some Dino test swirling in a bucket or through a paper towel.

In thinking it's both cyano and dinos?!
