I added some of Garfs Grunge a couple of weeks ago, and now have a bunch of little white spots appearing all over the place. Is this possibly coraline algae? When looking at them thru a 5x magnifying glass, they look like a 1 mm egg in the bottom of a frying pan. If this is coraline, when does it color-up, if it's not coraline...should I worry?
