This is one of the leading muck dive sites in Raja Ampat and divers often spend an entire day diving here. Many divers who arrive on this dive site for the first time initially believe that they have lost their direction or have misunderstood the navigation. They find themselves on a barren patch of ground that is in sharp contrast to the brimming aquarium like dive sites in the Dampier Straits or in Misool. This dive site, in particular, is well known for this experience but it is a fantastic muck diving site as it is made up of a large area of algae that give the dive site its name.

As with all muck diving sites, divers need to spend time searching and exploring to reveal the many different types of marine life that can be found amongst the algae and sand. One of the main inhabitants are ghost pipefish, and divers often spot many different types of species of this unique fish. Some of these are very carefully camouflaged and so look very similar to the seaweed strips that are twisting and drifting along in the current. Divers will have to look closer to see that these are actually a fish.

There are many small crustaceans including shrimps and crabs that can be found here, many of them using the area as a nesting area so it is common to find them holding on to their precious eggs. This is also a site known for seeing juvenile Wobbegong sharks but divers will need to have good guides with them to be able to spot the many different marine animals in this unique spot.
