Can you include a photo? This sounds like a fungal infection, but I want to be sure. You can use a peroxide when you water. Just replace 1/4 of the water with peroxide. This can stop a fungal infection, and add much needed oxygen into the soil.
I recommend watering only when the soil is almost completely dry on top to avoid any infections in the soil. Overwatering is the most common cause.https://www.gardeningknowhow.com/houseplants/arrowhead-plant/arrowhead-plant-care-arrowhead-plant-or-syngonium-podophyllum.htm
