    Maintaining a system that is as nutrient-free as possible is the goal of most saltwater aquarium hobbyists and many have come to accept the fact that protein skimmers are a necessity in any saltwater aquarium system. Island Aquatics carries a full line of protein skimmers and can help you choose the one that is right for you.
  • CALCIUM REACTORS
    For many reef aquarium hobbyists, dosing of required aquarium supplements presents it's own set of chores and headaches. Calcium reactors are an excellent choice for hobbyists who do not want to deal with the daily dosing of saltwater aquarium additives and supplements. Calcium reactors will enrich the water quality of your reef aquarium. They replace calcium and alkalinity supplements maximizing the growth of corals. Calcium reactors will also greatly increase the growth of coralline algae.
