I have a java fern in my 55 gallon tank, it has been set up for about 8 months now, all my parameters are good, water temp is 76 and i noticed that i am getting these black spots, on my java fern as well as the other taller plant in the pictures. I have been getting a lot of algae as well, green, brown, and even black when inside the tank, i keep wiping it off every few days but i cant seem to stop it. So is my plant dying, and what can i do to get rid of the algae growth?
