I have a major issue with green hair algae in my Evo 13.5 G tank. Tried taking as much out but they keep on coming back.

Any suggestions? Can't put a particular fish in the tank since the tank is pretty small. Any clean up crew tgat would eat this up or?

what type of lighting do you run? i had the same thing 2 years ago. I dropped my light output to 4 hours a day and it helped. then found out my t5 bulbs were putting out wrong spectrum/wavelength of light. changed bulbs, did a FULL cleaning of the tank (did cause a cycle but i was ready for that) and it hasnt came back.

I'm running the stock led lights. I did add two strips of blue leds rated at 460nm - 463nm and 14W both strips.
My stock blue/white led runs 9hrs and the blue led bars run 1hr before and 1hr after the stock lights turn on/off.

Have you tried lowering you phosphate to almost zero and up your WCs? You have to starve out the algae and maintain the tank that way.

Are you running the stock filter media? If so, that sponge could be a nitrate factory
