Describe your problem :
----------------------

I have had tropical fish about 15 years and a year ago started adding live plants to my 55 gallon aquarium. This past may I moved up to a 75 gallon aquarium with Java Fern, Anubias, and couple Amazon Swords. Two Months ago this Black Fuzz started growing, which i thought was kind of cool, but now it is becoming a Nuissacne and is everywhere and i dont know how to get rid of it and it seems from what I have been reading that i shoudl of handled this along time ago. i have been trying to read up on stuff through this site but I dont know much about plant stuff. So I beleive it is Brush Algae or Beard Algae, i have been seeing people say stuff about adding CO2 to their tanks, obviously this would help plants thrive, but how does this help with the algae and how do you inject the CO2 into the tank? Do you suggest i stop using my sponge filters, which airate the water alot. Here are some pics:









Thanks for your help!!!
