So i have these 3 zoa plugs that keep growing this algae on them that is has like the consistency of one of those roll out golf putter mats or like on a putt putt course. It doesn’t come off the plug at all with a tooth brush. I even put them in a 100% peroxide dip for 5-6 minutes yesterday and it did absolutely nothing to it. This is the best picture i can get of it
