Where i have my powerhead directed in my tank i am getting white fluffy algae on the branch it is pointing onto. Could anyone give me any suggestions as to how to get rid of or avoid this problem? I have tried redirecting it onto a different part of the tank but wherever i point the powerhead nozzle it just grows wherever it is pointed. I am also doing constant weekly 25% water changes. I have a couple of cory's in the tank but they do not seem to keen in munching it.
