I recently used some spare airline from an air pump to section off the floaters from being drawn into the skimmer. Today (less than a week since installing) I noticed the airline is stained pink. There is some slimey algae on the surface, this appears to be white when scraped off and floating in the water column. Some diatoms too. Snails don’t seem to mind it. It doesn’t appear to be removable. Could it be from the fish food (red granules)? Is it anything to be worried about? Or do anything about?
Thanks for reading!
