Coralline growing on ato sensor

[kim7]

Hello guys, my Autoaqua smart ato sensor has some corallline algae dots growing on it and im afraid that it might disrupt it in the future. Has anyone experienced this? It is pretty hard to scrape off. My 20g long reef is only 2 months old and im seeing smalls dots of coralline growth in my tank especially on my heater and my ato sensor.
