Loosing battle with bubble algae

[Frogger]

The red could be cyno bacteria. Over load of nutrients. I had a major outbreak when I was fighting byopsis with Fluconazole, got rid of the bryopsis got cyno, got rid of the cyno got dinoflagellates. Some times seems like a never ending cycle.

Algae turf scrubber?

I've had good luck with a simple upflow ATS to beat hair algae and cyano.

Instead of trying to kill it, grow something to out-compete it.

I have a friend with a 5g tank that put a a small submersible led light with some fabric in a back compartment that worked for him.
