How do you get rid of green algae?

Hello people, I’m growing in coco+perlite 70:30, I’ve noticed today there’s green algae growing on the top layer of the coco. For now I’ve placed foil paper on top of it to prevent the affected parts of coco from getting any light as green algae needs light to grow I’ve heard. Can I just remove the affected part of the algae and replace it with new coco? Also yes I know it’s due to excess watering, however the plant seems perfectly fine, not droopy or wilting. My temps are usually always around 27 celcius / 80 farenheit. RH is around 65% and drops down to 45% for a few minutes when the extractor fan kicks on.

I'm not entirely sure if this is correct, I would think a diluted mist of hydrogen peroxide would do the trick.

That's crazy you have algae on the top of your coco. The bottom outside of my cloth pots build up with algae but thats it. It wouldn't hurt to remove it and add more, i mean it doesn't look like alot. Wouldn't it just come back tho? I water everyday and im not experiencing that. Hmmm im curious what exactly is the issue here. Hopefully someone can chime in and hit us with some knowledge.

  • reduce nitrogen content
  • lower medium humidity (aka STOP OVER WATERING, but the other 2 are also growth factors for algae)
  • avoid light reaching medium

The algea is happening because of the over watering.

Even if your plant looks fine that already is due to the bad watering practice.

Also eventually your plant won't handle the over watering well.

Let it dry out a bit. Change habits and it will take care of itself.

But hydroponic or soilless hydroponic doesn't work like that. Two different growing styles.
