Help me figure out what type of algae this is

It is growing very rapidly and as you can see in the pic it is a long brown strand, it is growing all over the tank

Anybody?

Are there air bubbles present in it? If so it might be dinos. If not then its most likely slime or cyano.

In some spots it has bubbles in it like my sump but that is where there is bubbles formed by a little water fall on the baffles but on my rocks only a couple spots have bubbles but not connected to the algae

Most likely cyano or slime algae. Is any of it red or mainly brownish?

It almost looks orange-red in some places

I'd say cyano then. Try doing a big water change to see if it helps along with trying to vacuum it out. There are other methods to help but you may want to start there.

Update! it is dinoflagellates, bubbles everywhere in the algae and did a test I found on a different thread and found out it was Dino. Dosed h2o2
