Supplements

Have you ever wondered if you should be adding supplements to your saltwater aquarium? There's no single answer that fits every situation. The answer actually depends solely on what types of marine life you have in your home aquarium. If you have a fish only tank and do regular small water changes, you probably don't need to add anything to the tank. But, if you have invertebrates or corals in your tank you might need to add supplements to keep them healthy and thriving.

Saltwater consists of numerous elements at various concentrations referred to as PPM, or Parts Per Million. Although high quality saltwater mixes are designed to mimic these ratios as closely as possible, different brands, types and mixes have different concentrations of some of these elements. All of the elements that are found in the oceans water are crucial in keeping your fish, coral and other marine life healthy. And, as your aquarium runs, some of these elements can become depleted.
