Sorry guys I gave a bit of wrong info on the flatworms saying they are Photosynthetic. Here's a bit more information. filterpro.co.uk for biohome media and filter floss.
The Rust Brown Flatworm is the most common flatworm found in home aquariums. It is rust, brown or tan in color with a red dot and will reach a size of about 1/4". They are oval and somewhat elongated with two tail-like appendages. It has been identified as Convolutriloba retrogemma and reproduces rapidly in nutrient-rich marine aquariums. In high concentrations on a coral's surface, these flatworms can actually keep adequate light from reaching the corals, thereby "starving" the coral. Some believe that this flatworm also consumes the resident zooxanthellae on the coral's surface. This flatworm is normally found in areas of the aquarium with low water movement and can be seen on the surface of the corals.
