 Needs really cleaning. Needs a good cleaning. It is bad. Okay. You can do a light bleach solution or a light vinegar solution. Don't mix the two, one or the other. If it's a fountain, go ahead and run the fountain a little bit just to let the water go all the way through it. Good scrub brush. We've got some heavy-duty, strong-bristled scrub brushes in the store that are excellent for that kind of thing, getting the porous cracks and that kind of thing.
