Aquarium gravel substrate in a nature inspired sea Urchin Pink.
Manufactured in the UK from top quality natural river gravel which has been triple washed and carefully kiln dried before it is pink colour coated using an aquarium safe, non-toxic and durable polyurethane resin. The resulting product, either full colour or natural mix is both colourfast and waterproof.
This together with smooth rounded particle shape and inert neutral balance in water makes it ideal both for the hobbyist and for those wishing become even more creative with their aqua decor.
