Same way, blackout. But give it 5-6 days or so. However long the plants can

Don't, it can be controlled.

Well I can help you get rid of it. Afterwards ...is up to you.

Mini Riccia had some. It was a bit peaked at the end of the blackout but
remember plants can survive long shipments(but not heat).
R wallichii will sprout new growth afterwards.

Once you get rid of the algae, you next need to correct things.
More CO2/Traces/PO4, keep good tabs on NO3.

Prune well and trim old Anubias leaves etc.
I've found Green spot loves low CO2 and no PO4. More traces help.
It also likes light so at lower wattage, say 2 w/gal, the glass often is
cleaner longer.

You can treat specific plants by placing in a bag for a few days, or
covering with a small black plastic bag in the tank.

GS algae can be dealt with through PO4, CO2 and traces.
The hair algae can also be dealt with by using Amano shrimps, Rosey barbs

The routine for the blackout is the same, but try to get as much algae as
you can out first and then do the blackout for several days(4-7).

My algae was growing good when I started this routine. I did not place some
algae from another tank but cultured it in the tank to be treated.

If you add enough Amano shrimp, they will eat all the hair algae everytime.
