PJ reefs™ is dedicated to the husbandry of miniature saltwater environments. Typical saltwater aquariums require intricate and complex equipment, for the successful maintenance of corals and invertebrates. Through careful testing and measurements, PJ reefs™ has developed the very first low maintenance saltwater aquarium, that can contain certain corals and invertebrates. This allows anyone with an interest in saltwater aquariums to own and to enjoy a miniature reef.
