Ive notice all the really nice tanks have all that purple barnacacle growth on the walls, sides and equipment in tanks. It is starting in my tank , little spots of purple on the walls & on uvsterilizer.
What is the purple stuff called ? do you let it grow where ever it wants? I notice my fish nipping at it on the walls.
