Starting to notice little bit of algae that has a green color on parts of the moss rock water fall, not bad. Is this common for moss rock water falls? We have no issues with algae in the pool. Should I be concerned? Best way to get rid a of it? Brush it?
One more question, we just built and filled in Mach, best way to rid the white line of calcium that has started to show on tile? Any chemical to help with brushing it?
