Our LED’s our low maintenance. Our underwater lights are coated with an anti -barnacle/microrganism coating. This coating covers only the main part of the underwater light and not the top portion were light is transmitted through. We encourage the system to be powered on nightly. Operating from dusk to dawn will help eliminate barnacle/microrganism growth. If barnacle/microrganism growth were to occur, simply use a bristle brush (non-metal) to scrub the top of the LED and hose off. In the event excessive growth occurs, scrape with a plastic paint scraper. Nightly use of the Kraken Underwater Fish Light system will keep the LED portion clean.
