Teal and purple algae?

[Biglog]

I’m starting to get green algae and just noticed this bright teal and purple algae in the sand. Does anyone know what this is and how to get rid of it?

It looks like some types of cyanobacteria to me. I've found removing organics via water changes, more current, and more dissolved oxygen help to control it. If these things don't work, there are antibiotics and such for sale that can get rid of it.

Ultralife blue green slime remove will get rid of it, is not an antibiotic, and you don’t need to remove carbon if you need it. Light is casing that green spot algae and low flow is causing the bacteria. Those are causes, things like nutrients are simply the fuel.

Agreed, ultralife is the hobby's best kept secret

Definitely looks like cyanobacteria/blue green algae. I've used "Ultralife Blue Green Slime Stain Remover" in the past and it works like a charm. Doesn't harm fish or plants. I got it off of amazon for around $12.
