Do you ever have to clean refugium sand. I have about 3 inches of sand a few small pieces of rubble and a giant ball of cheato. It?s been set-up about 6 months and i feel like the top layer of sand has a lot of gunk on it. The only thing i ever do is trim the cheato. It appears healthy... lots of pod, bristle worms and snails. It doesn't feel right not to clean it.
thanks
