Help in getting rid of Green Algae

[Augustine_81]

Half of my 3ft tank is infested with green algae.
What is the fastest way to get rid of them other than scraping them out.
Currently , having 3 plecos, 10 albino discus, 6 tiger n zebra ottos in this planted tank.
They have spread like wild fire, covering my 3 driftwood and my us fissiden. (OMG!!!)
Hope to get a solution for it.
Thanks bro!!!

what green algae are you talking about? because most of algae are green

So first you need to identify what type of algae are you having with.

You said half of 3ft tank, the other half no algae? if so does the algae part of the tank receive direct sun light even if it is brief?
