Fig. 2. Schematic representation of a tubeworm maintenance aquarium. Sulfide dissolved in synthetic seawater (SSW) was introduced into the polyvinylchloride (PVC) hose, which was connected to PVC grating. The sulfide diffused out from the grating through the crushed coral and sediment layers. The aquarium was filled with SSW, which was kept aerated and filtered.
