I have been keeping an eye on my small pond and it seems that I have Algae growing on the walls and sides of my pond. Its also growing on the rocks, filter box and hoses that are under the water. I think its called carpet algae but im not sure. should I take a small sponge or pad to get rid of some of this algae? To me it's making the water look dirty. I can see my fish and the bottom of the pond without a problem. Any help would be great.
