Also, is the algae actually growing on the tank walls, plants and decorations? Or is it more like a great green cloud in the water itself? Sorry if this is a stupid question, but so many people mean so many different things when they say they have "green algae".

I would suggest for you to go to walmart and buy a Whisper 10-20i. It pumps 120gph and is suction cupped inside the tank or can be hung by a filter hanger which is included. I would suggest you to go to the petstore and buy REGULAR SIZE TETRATEC PRO II CARTRIDGES. Good luck!! I will continue to help!!!
