Sponges seem to pop up with greater enthusiasm in newer systems, newer systems tend to have increased levels of silicates, sponges like silicates. Once the tank evolves/ages the occurrence of sponges will decline. As stated above they are harmless, no intervention needed, they will die back to some degree over time, rarely does a sponge become invasive.
