Thanks for reaching out about Corn and including photos. This could be mineral deposits but is difficult to tell in the photos. Mold usually does not grow below the water level as needs oxygen. Clean the filter well. A sample of the material can be acquired and a veterinarian might be able to help by examining under the microscope. Good luck.
