Algae can stain silicone just like mold can stain it when used around a bath tub. I could probably be scrubbed clean but not recommend in an aquarium as it is get worked loose and cause leaks. Your tank looks nice even with the stained silicone because the rest of the tank is clean. Leave it be.So all of my corners in my aquarium are yellow on the silicone. Any clue why? Should I be worried about it?View attachment 308721
