They are probably building stuff with them...

Actually bioballs are still the preferred form of filtration for FO tanks. They are the fastest at converting ammonia to nitrate. Fish tolerate much higher levels of nitrate than corals, but the nitrates in these systems can still be kept low with good skimming (reducing the source) and water changing.
