Water Care

Water quality is the key to a happy aquarium. If you don’t have good water quality, you can’t expect to maintain a healthy, beautiful aquarium. Because tap water may contain additives, including chlorine and fluoride, and distilled water lacks the necessary minerals, neither option is naturally ideal for your underwater critters. Whether you have live plants or a plethora of fish, you must create the right environment for their health. Choose aquarium water treatments from Modern Aquarium to ensure effective aquarium water care today!
