Brown algae on my sword plants?

[Jesselav1233]

So I've had my sword plants a few months now and they have got this thick brown algae on them I can rub it off and the plant otherwise seems healthy what is it? I cleaned it all off by just rubbing it off with my hands but there is still a little on in spots that won't come off is there a way to kill it? This is in my discus tank so I'm really scared to put anything in the water on account of how temperamental they can be to any change in their water condition. Thanks for any advice

Can you post a pic? It's probably diatoms.

How old is the tank?

How old is the tank?

Its been set up about 3 months now

If I remember correctly it happens in every tank, mostly newly set up ones. Although it may look ugly, it's not harmful.

How often do you fertilize?

Never have used it I tried using flourish excel once but my discus didn't like it so I never used it again

Will it stop growing eventually or is it going to keep coming back?

It should go away on it's own.
