The Volcano was created to personalise your Reef One aquarium. It is made from materials that are totally safe for aquatic life. Designed as a single ornament to cover the centre bubble tube and pre-fitted with a varied selection of synthetic plants. Two sizes are available, a small version for the biOrb 30L (8 US Gallons) and a taller version for the biUbe 35L (9 US Gallons) and biOrb 60L (16 US Gallons). The volcano is easily removed for aquarium cleaning and eliminates the need to reposition the plants afterwards.
