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
